x^(2//3) + x^(4//3) =...

`x^(2//3) + x^(4//3) = `

A

`x^(2//3)`

B

`x^(8//9)`

C

`x`

D

`x^(2//3) ( x^(2//3) + 1)`

Text Solution

Verified by Experts

The correct Answer is:
D
Factor out `x^(2//3)` , the greatest common factor of `x^(2//3) + x^(4//3) , ` to get `x^(2//3) + x^(4//3) = x^(2//3) ( 1 + x ^(2//3)) `.
