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..... :-)
