Question

what is the least rationalising factor of under root 8

Answer 1

hey mate here is ur ans
--------------------------------------
rationalising means making an surd into rational number
here
√8=√4*√2
√8=2*√2
=2√2
then here i simplified that question i got
2√2
i have said that rationlising means converting into rational
here 2√2 is not a rational
so, im converting
im multiplying 2√2 by √2 THEN we get
4 as number
here, 4 is a rational number so, rationalising factor of √8 is √2

Thank you
hope it helps u
if u satisfy mark as brainliest

Answer 2

√8×√2= √16=4
hence the rationalising factor of root 8 is root 2
