Question

Evaluate the following expressions, and justify your answers.
WhatPower1/3(9)

Answer 1

correct answer is -2

Explanation:

given data as per question

WhatPower1/3(9)

to find out

Evaluate the expressions WhatPower1/3(9)

solution

so here we know that whatpower mean exponent of equation so we get by given equation

so

we know WhatPower1/3(9) = -2

because here

we know that
`(1)/(3) * (1)/(3)` =
`(1)/(9)`

but we want only 9

so
`(1)/((1)/(3)) * (1)/((1)/(3))` = 9

so exponent is -2

so here we can say that

`((1)/(3))^(-2)` = 9

so that the exponent is here -2 of
`(1)/(3)` that become 9

so correct answer is -2
