Rationalise the denominator-
2+√3/2-√3
For class 9​

Answer 1

Answer:

7

Step-by-step explanation:

First, rationalise the denominator by multiplying the top and bottom of the fraction by the conjugate of the denominator.(2/(3-sqrt(2)))((3+sqrt(2))/(3+sqrt(2)))Next, expand the brackets - notice there will be a difference of two squares on the bottom of the fraction.(6+(2sqrt(2)))/(9-2)Finally, simplify your answer.(6+2*(sqrt(2)))/7
