Answer 2

Answer:

Rationalise the denominator of 1/(root 7 + root 6 - root 13)

here is the similar question

Rationalising the denominator : If the denominator of the expression contains a term with a square root or a number under the radical sign then the process of converting it to an equivalent expression whose denominator is a rational number , is called rationalising the denominator.

•Conjugate of (√a + b) is (√a-b) & Conjugate of (√a - √ b) is (√a + √b).

For Rationalising the denominator , we will multiply the numerator and denominator by conjugate of denominator to remove the radical sign form the denominator.
