Question

Write each expression using a positive exponent for the given problems below. Use each box for each part of the fraction. There is also a box for the exponent on the number in the denominator.

Answer 1

The given expression is:

$7^{-10}$

It is required to write the expression using a positive exponent.

Recall the Negative Exponent Property which states for any nonzero real number a and integer n the following is true:

$a^{-n}=\frac{1}{a^n}$

Substitute a=7 and n=10 into the equation:

$7^{-10}=\frac{1}{7^{10}}$

Hence, the answer is 1/7¹⁰.
