What is m^-2timesm^-3?

Dec 10, 2016

${m}^{-} 5$

Explanation:

The rule for multiplying common terms with exponents is:

$\textcolor{red}{{x}^{a} \times {x}^{b} = {x}^{a + b}}$

Using this rule for the expression in the problem gives:

${m}^{-} 2 \times {m}^{-} 3 \to {m}^{- 2 + - 3} \to {m}^{-} 5$
