What is the value of the expression 3/3^-2 ?
A. 27
B. 18
C. 1/2
D. 1/3

Answer 1

\[\frac{ 1 }{ a^{-1} } = 1\div \frac{ 1 }{ a } \rightarrow 1 \times \frac{ a }{ 1 } = a\]

Answer 2

We can use that basic idea for your problem now\[\frac{ 3 }{ 3^{-2}} = 3 \div \frac{ 1 }{ 3^2 } = 3 \times 3^2 = 27\]
