Question

Rationalise the denominator in the 5 + root 6 / 5- root 6

Answer 1

Step-by-step explanation:

We have:-

5+√6

5-√6

Multiplying Numerator and Denominator by 5+√6.(Since Denominator is to be rationalised)

We get:-

(5+√6)(5+√6)

(5-√6)(5+√6)

=(5+√6)^2

5^2-(√6)^2

=25+6+10√6

25-6

=31+10√6/19
