# Rationalise the denominators of the following:i. ii. iii. iv.

i.

Here, the conjugate of the denominator (3 + √2) is (3 - √2).

By rationalizing,

We know that (a + √b) (a - √b) = a2 – b.

ii.

Here, the conjugate of the denominator (√7 - √6) is (√7 + √6).

By rationalizing,

We know that (√a + √b) (√a - √b) = a – b.

iii.

By rationalizing the denominator,

iv.

Here, the conjugate of the denominator (√3 - √2) is (√3 + √2).

By rationalizing,

We know that (√a + √b) (√a - √b) = a – b.
