Question

3

Select the correct answer.
3567745
, if x+ 0 and y+ 0?
Which expression is equivalent to
OA 2x2y Try?
OB. 8ry87 24 y²
OC. 8x273/7xy2
OD. 2x422977

Answer 1

Option A

Explanation:

Given expression is
`\sqrt[3]{56x^7y^5}`.

`\sqrt[3]{56x^7y^5}=(56x^7y^5)^{(1)/(3)}`

`=[(2)^3(7)(x^2)^3(x)(y)^3(y)^2]^{(1)/(3)}`

`=[(2)^{(3)/(3) }(7)^{(1)/(3) }(x^2)^{(3)/(3) }(x)^{(1)/(3)}(y)^{(3)/(3) }(y)^{(2)/(3) }]`

`=3x^2y[(7)^{(1)/(3)}(x)^{(1)/(3)}(y^2)^{(1)/(3)}]`

`=3x^2y\sqrt[3]{7xy^2}`

Option A is the correct option.
