Question

Which shows how to find the value of this expression when x = negative 2 and y = 5?

(3 x cubed y Superscript negative 2 Baseline) squared
StartFraction 3 squared (negative 2) Superscript 6 Baseline Over 5 Superscript 4 EndFraction
StartFraction 3 (negative 2) Superscript 6 Baseline Over 5 Superscript 4 EndFraction
StartFraction 3 squared (5 Superscript 6 Baseline) Over (negative 2) Superscript negative 4 Baseline EndFraction
StartFraction 3 Over (2) Superscript 6 Baseline 5 Superscript 4 Baseline EndFraction

Answer 1

A

Explanation:

I took the test on edge

Answer 2

(A)
`(3^2(-2)^6)/(5^(4))`

Explanation:

Given the expression;

`(3x^3y^(-2))^2`

When x=-2, y=5

We have:

`(3(-2)^3(5)^(-2))^2=3^2\cdot(-2)^6\cdot5^(-4)\\=(3^2\cdot(-2)^6)/(5^(4))`

The correct option is A

StartFraction 3 squared (negative 2) Superscript 6 Baseline Over 5 Superscript 4 EndFraction
