The procedure of multiplying a surd by another surd to get a rational number is called RationalisationThe operands are called Rationalizing Factor (RF) of the other.Here,

2

is the Rationalisation Factor.

Answer 2

B. √32

factors: 2×2×2×2×2

=4√2

to rationalize 4√2 multiple it with √2

√32×√2

√64

√8×8

:8

simplest rationalizinc factor is √2

C. 2√5

simplest rationalizinc factor is √5

D.√3-√2

simplest rationalizing factor of √3-√2 is. √3-√2

E. √2+√3+√7

simplest rationalizing factor of √2+√3+√7 is √2-√3-√7
