31-216
(-2)4
21954

Answer 1

he's right it's A because i just took the test and i got it right

Explanation:

Answer 2

Option 1 is correct

Explanation:

Given expression is:

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

Putting the values

`= [3 (-2)^3 (5)^(-2)]^2\\We\ have\ to\ make\ the\ powers\ positive\\= [{(3(-2)^3)/(5^(2)) }]^2\\= \frac{[{3(-2)^3}]^2}{(5^2)^2} \\Applying\ outer\ power\\= (3^2(-2)^6)/(5^4) \\`

Hence option one is correct ..
