Answer» _____________________ (6 - 4√2) / (6 + 4√2) • By rationalizing the denominator :- = (6 - 4√2)(6 - 4√2) / (6 + 4√2)(6 - 4√2) = (6 - 4√2)² / [ (6)² - (4√2)² ] = (6² + 4√2² - 2 × 6 × 4√2) / (36 - 32) = (36 + 32 - 48√2) / 4 = (68 - 48√2) / 4 = [ 4(17 - 12√2) ] / 4 • 4 cancels in the numerator and the denominator :- = 17 - 12√2 _____________________

(6 - 4√2) / (6 + 4√2)

• By rationalizing the denominator :-

= (6 - 4√2)(6 - 4√2) / (6 + 4√2)(6 - 4√2)

= (6 - 4√2)² / [ (6)² - (4√2)² ]

= (6² + 4√2² - 2 × 6 × 4√2) / (36 - 32)

= (36 + 32 - 48√2) / 4

= (68 - 48√2) / 4

= [ 4(17 - 12√2) ] / 4

• 4 cancels in the numerator and the denominator :-
