Chapter 7 - Exponents and Exponential Functions - Mid-Chapter Quiz: 1

Answer

$\frac{1}{45}$

Work Step by Step

We start with the given expression: $5^{-1}3^{-2}$ The negative exponent rule states that for every nonzero number $a$ and integer $n$, $a^{-n}=\frac{1}{a^n}$. We use this rule to rewrite the expression: $\frac{1}{5^13^2}$ We expand the exponents on the denominator and multiply: $\frac{1}{5\times3\times3}=\frac{1}{45}$
