Question

Evaluate the expression:(1/7)³ = ?

Answer 1

The given expression is

$(\frac{1}{7})^3$

In order to evaluate this expression, we need to use the following property

$(\frac{a}{b})^n=\frac{a^n}{b^n}$

That is, we must assign the exponent number to each part of the fraction, then we solve

$\frac{1^3}{7^3}=\frac{1\cdot1\cdot1}{7\cdot7\cdot7}=\frac{1}{343}$

Therefore, the answer is 1/343.
