Answer 2

=>. 2 / √5 - √√3

RATIONALISING THE DENOMINATOR OF. 2 / √5 - √√3 ;

NOW , MULTIPLYING THE NUMERATOR AND DENOMINATOR OF IRRATIONAL BY √5 + √3 ,WE GET ;

=>. 2 / √5 - √√3 × √5 + √3/ √ 5 + √3

=>. 2( √5 + √3) / (√5 × √5 ) + ( √3 × √3)

=>. 2 √ 5 + 2√ 3 / (√5) ^2 + (√3) ^ 2

=>. 2√5 + 2√3. /. 5. + 3

=>. 2√5 +. 2√3 / 8

SO THE RATIONALISED DENOMINATOR OF 2 / √5 - √√3 IS 2√5 +. 2√3 / 8 .
