Answer:3 - √2 / 3 + √2
Multiply the numerator and the denominator with their rationalizing factor.
= (3 - √2)/(3 + √2) * (3 - √2)/(3 - √2)
= (3 - √2)^2 / (3)^2 - (√2)^2
= (3)^2 + (√2)^2 - 2*3*√2 / 9 - 2
= 9 + 2 - 6√2 / 7
= 11 - 6√2 / 7
Therefore after rationalisation , the answer will be...
11 - 6√2 / 7... please mark me as brainly for helping you! thanks!
