Can you write the expression using the Equation button at the bottom left?

Answer 2

negative exponents aren't allowed...therefore they are written as 1 / whatever the number is so .. for 5^-1 we have 1/5^1 which is 1/5.
for 3^-2 we hace 1/3^2 which is 1/9
1/5 multiplied by 1/9 is 1/45

Answer 3

\[5^{-1}\]
\[\frac{ 1 }{ 5^1 }\]
\[\frac{ 1 }{ 5 }\]

Answer 4

\[3^{-2}\]
\[\frac{ 1 }{ 3^2}\]
\[\frac{ 1 }{ 9}\]

Answer 5

\[\frac{ 1 }{ 9}\] X \[\frac{ 1 }{ 5}\] =
\[\frac{ 1 }{ 45}\]
