Question

Exponents and powers chapter question pls answer

Answer 1

16

Explanation:

first , there is a 5^3 in numerator which gives us

125 , so we can cancel both 125 in numerator and denominator

we left with threes

there are two threes in numerator and denominator one of them is negative sign , if we divide them it gonna be

-1

now -2^4 = -16

-16 ( - 1 ) = 16

Answer 2

- 16

Explanation:

Evaluate the exponents on numerator/ denominator, that is

`(16(125)(-243))/(125(243))`

Cancel 125 and 243 on numerator/ denominator, leaving

`(16(-1))/(1)` = - 16
