Question

Rationalize the denominator:
3
5 − √6

Answer 1

Step-by-step explanation:

3/5-√6

Multiplying the fraction by 5+√6

(As whenever you rationalise you have to put the same no as of the denominator but the sign has to be opposite ex:if 2+√5 is given you have to multiply the fraction with the no as same of the denominator but the sign is to be opposite that is 2-√5)

3/5-√6*3+√6/3+√6

3*(5+√6)/5-√6*5+√6

Now (a-b)(a+b)=a^2-b^2

15+3√6/5^2-√6^2

√6^2=6

15+3√6/25-6

15+3√6/21

Ans is :15+3√6/21
