Hiii friend,


5✓3-4✓2/4✓3+3✓2


Rationalizing the denominator 4✓3+3✓2


=>. 5✓3-4✓2/4✓3+3✓2 × 4✓3-3✓2/4✓3-3✓2



we know that,



(A+B)(A-B) = A²-B²


So,


=> (5✓3-4✓2)(4✓3-3✓2)/(4✓3+3✓2)(4✓3-3✓2)


=> 5✓3(4✓3-3✓2)-4✓2(4✓3-3✓2)/(4✓3)² - (3✓2)²


=> 20 × 3 - 15✓6 - 16✓6 + 12 × 2 / 48 - 18


=> 60 - 31✓6 + 24/30


=> 84-31✓6/30


HOPE IT WILL HELP YOU..... :-)
