Step 2: Press the exponentiation key
The exponentiation key on the TI30X IIS is the “^” key. Press this key to enter the exponent. In our example, we would press the “^” key three times to enter the exponent 3.
Step 3: Press the enter key
Finally, press the enter key to calculate the exponentiation. The answer, 8, will be displayed on the screen.
That’s it! You have now learned how to do negative exponents on the TI30X IIS. This is a simple but useful skill that can be used to solve a variety of mathematical problems.
Step  Explanation  Example 

Enter the base number.  The base number is the number that will be raised to a power.  10 
Press the exponent key (^).  The exponent key is located to the left of the equals sign (=).  ^ 
Enter the exponent.  The exponent is the power to which the base number will be raised.  2 
Press the enter key ().  The calculator will display the answer.  10^(2) = 0.01 
Entering a Negative Exponent
To enter a negative exponent on the TI30X IIS, follow these steps:
1. Press the 2nd button.
2. Press the ^ button.
3. Enter the base number.
4. Press the – button.
5. Enter the exponent.
For example, to enter the expression `5^(2)`, you would press the following keys:
2nd
^
5
–
2
The display will show the following:
5^(2)
Evaluating a Negative Exponent
To evaluate a negative exponent on the TI30X IIS, follow these steps:
1. Enter the expression.
2. Press the Enter button.
The calculator will evaluate the expression and display the result.
For example, to evaluate the expression `5^(2)`, you would press the following keys:
5^(2)
Enter
The display will show the following:
0.04
The TI30X IIS can be used to enter and evaluate negative exponents. To enter a negative exponent, press the 2nd button, the ^ button, the base number, the – button, and the exponent. To evaluate a negative exponent, enter the expression and press the Enter button.
Using negative exponents in calculations
Negative exponents can be used in a variety of calculations, including:
 Multiplying two numbers with the same base. To multiply two numbers with the same base, you can raise the base to the power of the sum of the exponents. For example, to multiply 2^3 by 2^5, you would raise 2 to the power of 3 + 5 = 8. This gives you 2^8 = 256.
 Dividing two numbers with the same base. To divide two numbers with the same base, you can raise the base to the power of the difference of the exponents. For example, to divide 2^5 by 2^3, you would raise 2 to the power of 5 – 3 = 2. This gives you 2^2 = 4.
 Raising a number to a negative power. To raise a number to a negative power, you can take the reciprocal of the number raised to the positive power. For example, to raise 2 to the power of 3, you would take the reciprocal of 2^3 = 8, which is 1 / 8.
Troubleshooting negative exponents
If you are having trouble with negative exponents, there are a few things you can check.
 Make sure you are entering the exponent correctly. Negative exponents can be entered as a number with a negative sign, or as a fraction with a numerator of 1 and a denominator that is the negative exponent. For example, 3 can be entered as 3 or as 1 / 3.
 Make sure you are using the correct order of operations. When evaluating expressions with negative exponents, you need to follow the order of operations. This means that you should perform exponentiation before multiplication or division. For example, 2^3 * 2^5 should be evaluated as (2^3) * (2^5) = 2^2 = 4.
 Check your calculator settings. Some calculators have a setting that allows you to enter negative exponents as a number with a negative sign, or as a fraction with a numerator of 1 and a denominator that is the negative exponent. If you are not sure which setting your calculator is using, consult the owner’s manual.
Negative exponents can be a bit tricky to understand at first, but they are actually quite simple once you get the hang of them. By following the tips in this article, you can easily use negative exponents in your calculations.
How do I do negative exponents on a TI30X IIS?
1. Press the 2nd button and then the ^ button to enter exponent mode.
2. Enter the base number.
3. Press the – button to enter the negative exponent.
4. Press the Enter button to calculate the result.
What is the difference between a negative exponent and a positive exponent?
A negative exponent means that the base number is raised to the power of a negative number. For example, 3^2 means 1 / 3^2.
A positive exponent means that the base number is raised to the power of a positive number. For example, 3^2 means 3 * 3.
Can I use negative exponents to solve equations?
Yes, you can use negative exponents to solve equations. For example, to solve the equation 3^x = 9, you would first take the logarithm of both sides of the equation: log(3^x) = log(9). Then, you would use the power rule of logarithms to bring the exponent down: x * log(3) = log(9). Finally, you would divide both sides of the equation by log(3) to get x = log(9) / log(3).
What are some other common uses for negative exponents?
Negative exponents are often used to express very small numbers. For example, 10^5 is equal to 0.00001. Negative exponents are also used to express the reciprocal of a number. For example, 1 / 2 can be written as 2^1.
In this tutorial, we have discussed how to do negative exponents on the TI30X IIS calculator. We first discussed the difference between positive and negative exponents, and then we showed you how to enter negative exponents into the calculator. Finally, we showed you how to use negative exponents to solve problems.
