Question

Cube root 4/w^2 #rationalize the denominator

Answer 1

[4/w²]^1/3 = 4^1/3 / w^2/3 has an irrational denominator BECAUSE w has a fractional exponent.

 

To cure tdhis, multiply both numerator & denominator by w^1/3

 

Final answer will have cube root of 4w in numerator, and the denominator will be w.
