Answer 2

Answer:

(i) 16/9

(ii) -125/64

(iii) 81/16

(iv)243/-3125

Step-by-step explanation:

(i) When something is squared it means it is multiplied by itself so-

$\frac{-4}{3} *\frac{-4}{3}$

So -4x-4=16

And 3x3=9

16/9

(ii) Same here,

$\frac{-5}{4} *\frac{-5}{4} *\frac{-5}{4}$

-5x-5x-5=-125

4x4x4=64

125/64=1 61/64

(iii) 3x3x3x3/-2 x-2 x-2 x-2

81/16

(iv)3x3x3x3x3/-5 x -5 x -5 x -5 x -5

243/-3125
