Write the lowest rationalising factor of √5 - 3.

बेरीज

(√5 - 3)(√5 + 3) = (√5)² - (3)² = 5 - 9 = -4

∴ lowest rationalizing factor is (√5 + 3)

Rationalize the denominator.

`1/sqrt14`

Write the simplest form of rationalising factor for the given surd.

`sqrt 50`

Write the simplest form of rationalising factor for the given surd.

`sqrt 27`

Write the lowest rationalising factor of : √18 - √50

Write the lowest rationalising factor of 15 – 3√2.

Find the values of 'a' and 'b' in each of the following:
`( sqrt7 - 2 )/( sqrt7 + 2 ) = asqrt7 + b`

If x =`[sqrt5 - 2 ]/[ sqrt5 + 2]` and y = `[ sqrt5 + 2]/[ sqrt5 - 2 ]`; find :
x²

If x = 5 - 2√6, find `x^2 + 1/x^2`

If `[ 2 + sqrt5 ]/[ 2 - sqrt5] = x and [2 - sqrt5 ]/[ 2 + sqrt5] = y`; find the value of x² - y².

Rationalise the denominator and simplify `(2sqrt(6) - sqrt(5))/(3sqrt(5) - 2sqrt(6))`
