Answer:

correct answer is -2

Step-by-step 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   [tex]\frac{1}{3} * \frac{1}{3}[/tex]  = [tex]\frac{1}{9}[/tex]

but we want only 9

so [tex]\frac{1}{\frac{1}{3}} * \frac{1}{\frac{1}{3}}[/tex]  = 9

so exponent is -2

so here we can say that

[tex](\frac{1}{3})^{-2}[/tex]  = 9

so that  the exponent  is here -2 of [tex]\frac{1}{3}[/tex]  that become 9

so correct answer is -2
