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 32`

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

`sqrt 50`

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

`3/5 sqrt 10`

Write the lowest rationalising factor of : √13 + 3

If x =`[sqrt5 - 2 ]/[ sqrt5 + 2]` and y = `[ sqrt5 + 2]/[ sqrt5 - 2 ]`; find : y²

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

If x = 2√3 + 2√2, find: `(x + 1/x)`

If x = 1 - √2, find the value of `( x - 1/x )^3`

Evaluate: `( 4 - √5 )/( 4 + √5 ) + ( 4 + √5 )/( 4 - √5 )`
