# What is the least rationalising factor of √44?√5 √2 √43 √11

Solution

## The correct option is D √11 We can write 44 as 2×2×11 ⇒√44=√2×2×11 =2√11 The rationalizing factor should be such that if we multiply it with 2√11, we get a rational number.  Hence, the least rationalizing factor is √11 as 2√11×√11=2×11=22, which is a rational number
