Question

Rationalising factor of cube root 32

Answer 1

cube root 32= cube root(2×2×2×2×2)
= 2× cube root(2×2)
so if we multiply cube root 2 to the above no. then it will become a rational no. I.e., 2×2=4
•°• The rationalising factor of cube root 32 is cube root 2

Answer 2

Answer:AR17 has correct answer but wrong method. The answer is cube root of 2

Step-by-step explanation:

cube root of 32 = cube root of (2*2*2*2*2)

= 4 * cube root of 2. So cube root of 2 should again be multiplied. As this is cube root and not square root, cube root of 2 should me multiplied 2 times. Thanks!!!
