(3+ √7)/(3- √7)

We have to rationalize 3 - √7 by multiplying 3 + √7 with the numerator as well as denominator.

[(3 + √7)/(3 - √7)] *(3 +√7)

(3 + √7)²/(3)² - (√7)²

[(3)²+(√7)²+2*3*√7]/9-7

(9+7+6√7)/2

(16+6√7)/2

2(8+3√7)/2

8+3√7

so, a= 8 and b=3√7

Genius145: 16 is divisible by 4 but 6 is not divisible by 4.6 is divisible by 3 but 16 is not divisible by 3

nafuali: i means to say that in factorisation we take common no but here in denominator we had not done any type of factorization

nafuali: so how 2 is common

Genius145: we have to take common only in numerator in this question . In denominator if there is any common factor then we have to take it out.

nafuali: so 16 and 6 are common

nafuali: thanks

Genius145: because 2 is the only number that is divisible by both 16 and 6.

nafuali: ok

Genius145: welcome. I hope you understood it.

Genius145: please mark my answer as brainliest if it satisfied you
