Question

Please Rationalise.......
I am not able to do​

Answer 1

Step-by-step explanation:

When the denominator is of form √a +√b or vice versa We multiply and divide the number with √a -√b or vice versa.

4/2+√3+√7

=> 4/2 +4/√3+√7 [ Splitting the rational and irrational parts into fractions]

=> 2+ 4(√3-√7/(√3+√7)(√3-√7)

=> 2+ 4(√3-√7)/ (√3)^2-(√7)^2

=> 2+4(√3-√7/3-7

=> 2+4(√3-√7/-4

=>2-√3+√7
