Question

Write the fraction as a expression using a negative exponent other than -1

Answer 1

First, write 81 as a power, in this case, we know that the square root of 81 is 9, then,

`81=9^2`

then, we can rewrite the expression as:

`(1)/(9^2)`

since the power is at the denominator, we can write it in the numerator using a negative exponent,

`\begin{gathered} 1*9^(-2) \\ \end{gathered}`

Answer:

`(1)/(81)=9^(-2)`
