Question

Rationalise 1 + root 3 by 1 minus root 3

Answer 1

(1+√3)/1-√3

=(1+√3)(1+√3)/(1-√3)*(1+√3)

=(1+2√3+3)/1-3

=-(4+2√3)/2

=-2(2+√3)/2

=-2-√3

Answer 2

Answer:

1+root3/1-root3

(1+root3/1-root3)×(1+root3/1+root3)

(1+root3)^2/(1-root3^2)

(1+root3^2+2.root3)/(1-root3^2)

(1+3+2root3)/(1-3)

(4+2root3)/(-2)

2 (2+root3)/(-2)

-(2+root3)

-2-root3
