Evaluate the following expressions, and justify your answers.WhatPower1/3(9)
Accepted Solution
A:
Answer:correct answer is -2Step-by-step explanation:given data as per questionWhatPower1/3(9)to find outEvaluate the expressions WhatPower1/3(9)solution so here we know that whatpower mean exponent of equation so we get by given equation sowe know WhatPower1/3(9) = -2because 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] = 9so exponent is -2 so here we can say that [tex](\frac{1}{3})^{-2}[/tex] = 9so that the exponent is here -2 of [tex]\frac{1}{3}[/tex] that become 9so correct answer is -2
