How do you evaluate negative powers?
Apply the Negative Exponent Rule. Negative exponents in the numerator get moved to the denominator and become positive exponents. Negative exponents in the denominator get moved to the numerator and become positive exponents. Only move the negative exponents.
What is the negative of 3?
For example, negative three is the result of subtracting three from zero: 0 − 3 = −3. In general, the subtraction of a larger number from a smaller yields a negative result, with the magnitude of the result being the difference between the two numbers.

What is 2 with the power of 3?
Answer: 2 raised to the third power is equal to 23 = 8. Explanation: 2 to the 3rd power can be written as 23 = 2 × 2 × 2, as 2 is multiplied by itself 3 times. Here, 2 is called the “base” and 3 is called the “exponent” or “power.”
When to use negative exponent in power calculator?
A negative exponent represents which fraction of the base, the solution is. To simplify exponents with power in the form of fractions, use our exponent calculator. Calculate the exponent for the 3 raised to the power of 4 ( 3 to the power of 4 ).
How to evaluate an expression with a power?
1 Evaluate all powers from left to right. Raising a number to a power simply means multiplying the number by itself that many times. 2 Evaluate all multiplication and division from left to right. 3 Evaluate addition and subtraction from left to right.
Is the exponent of 2 times 2 no longer negative?
Now that you have a fraction, and the exponent is no longer negative, you will keep 1 as the numerator and have 2 ⋅ 2 ⋅ 2 as the denominator. You can simplify the denominator. 2 times 2 is 4 times 2 again, is 8. The numerator is 1 and the denominator is 8, which is the fraction 1 8.
What is the value of exponent for 2 raised to the power calculator?
2 raised to the power calculator. What is the value of exponent for 2 raise to power 9 (2 to the 9th power) Therefore the exponent is 512. How do you calculate the exponents of 5,6,7 to the power of 4? Therefore the exponents are 625, 1296, 2401.
