Question

Simplify these expressions:

 

A) {(2x^2y^3)÷(3xy^4)}^2

 

B) {(x^3y^-2)÷(x^-1y^5)}^-1

Answer 1

A). {(2x²y³) ÷ (3xy⁴)}² = {(2/3)xy^-1}² = (4/9)x²y^-2  

 

                                                      = 4x²/(9y²)

 

    -------------------------------------------------------------

 

B). {(x³y^-2) ÷ (x^-1y⁵)}^-1 = {x⁴y^-7}^-1

 

                                  = x^-4y⁷ = y⁷/x⁴ 

Answer 2

I saw that I had mis-read the problem and tried to edit it, but the screen came up in code, rather than as it usually appears, so I couldn't edit it. So I deleted it, but the system won't let me update it with blank space, so I'm giving this explanation.

Answer 3

2x²y³/(3xy⁴)²=(2/9)/y⁵
