Question

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

Answer 1

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   $\frac{1}{3} * \frac{1}{3}$  = $\frac{1}{9}$

but we want only 9

so $\frac{1}{\frac{1}{3}} * \frac{1}{\frac{1}{3}}$  = 9

so exponent is -2

so here we can say that

$(\frac{1}{3})^{-2}$  = 9

so that  the exponent  is here -2 of $\frac{1}{3}$  that become 9

so correct answer is -2
