Question

Find the simplest rationalising factor of (a) root 64 (b) ³root 32​

Answer 1

Answer:

a)1 b)∛2

Step-by-step explanation:

√64 = √8²=8

8 is already a rational number so the rationalising factor is 1.

∛32=∛8x4=∛2³x4=2 x∛4

∛4 when multiplied by∛2 -

∛4x2=∛2³=2

2 is a rational number hence rationalised
