Chapter 4.6, Problem 6C

To determine

To write the expression $\frac{1}{1000}$ without using the fraction bar.

Answer to Problem 6C

  ${10}^{-3}$

Explanation of Solution

Given information: $\frac{1}{1000}$

To write the expression using positive exponents.

  $\frac{1}{1000}$

Hence it further becomes

  $=\frac{1}{{10}^3}$

  $={10}^{-3}$ Since 1000 can be denoted as ${10}^3$ and if its position is changed in the fraction, the sign of the exponent reverses for positive to negative and vice versa.
