Question

Which expression is equivalent to Assume x > 0 and y 0.

Answer 1

the answer is radical 5 over x^2 y 

Answer 2

we have

`\sqrt{(55x^(7)y^(6))/(11x^(11)y^(8))}`

we know that

`\sqrt{(55x^(7)y^(6))/(11x^(11)y^(8))} =\sqrt{(55)/(11)(x^(7))/(x^(11))(y^(6))/(y^(8))} \\ \\= \sqrt{(5)/(x^(4) y^(2))} \\ \\ =(√(5))/(x^(2) y)`

therefore

the answer is

The expression equivalent is
`(√(5))/(x^(2) y)`
