To determine

To write the expression $\frac{x^7}{z^2}$ without using the fraction bar.

Answer to Problem 8C

  $x^7{z}^{-2}$

Explanation of Solution

Given information: $\frac{x^7}{z^2}$

To write the expression using positive exponents.

  $\frac{x^7}{z^2}$

  $=x^7{z}^{-2}$ after changing position of ‘z’ in the fraction, the sign of the exponent reverses for positive to negative and vice versa.
