Therefore any fraction raised to this type of exponent shall be equal to the unit divided by this rational base power but raised to a positive exponent. Match each exponential expression to the equivalent fraction raised to a power. It means 3 4.

Since this is just a geometric series. For more complex fractions. The base 2 raised to the power of minus 3 is equal to 1 divided by the base 2 raised to the power of 3.

Where a b ab a b and c c c are integers. The correct answer for a fraction with exponents will always be a. Therefore the exponent is 81.

Raising to integer powers greater than 0 1 2 3 Another basic that Id like to clear is the exponent. To calculate exponents such as 2 raised to the power of 2 you would enter 2 raised to the fraction power of 21 or 2 2 1. 2 squared 2 x 2 4 so invert this for 12 squared.

To calculate radicals such as the square root of 16 you would enter 16 raised to the power of 12. Answered Nov 10 16 at 157. We raise both top and bottom of the fraction to the exponent n.
