Rewrite using a single positive exponent.

9^5/9^2

9^(5-2)

To rewrite the expression using a single positive exponent, we can subtract the exponents:

9^(5-2)

Simplifying the exponent:

9^3

To rewrite the expression using a single positive exponent, we need to combine the exponents in the numerator and denominator.

The expression is: 9^5 / 9^2

When we divide two numbers with the same base (here, 9), we subtract the exponents. Thus, we subtract the exponent in the denominator from the exponent in the numerator.

9^5 / 9^2 = 9^(5 - 2)

Simplifying further:

9^(5 - 2) = 9^3

Therefore, the expression 9^5 / 9^2 can be rewritten as 9^3.
