Answer 1

Step-by-step explanation:

1) m2 = 1/ 3-2√2

m= √1/3-2√2

= 1/√3-2√2

simillarly n2

3) mn

1/3-2√2 * 1/3+2√2

do like this you can solve this

Answer 2

$\huge\boxed{Answer}$

m = 1/(3 - 2√2) × (3 + 2√2)/(3 + 2√2)

m = (3 + 2√2) / (3 - 2√2)(3 + 2√2)

m = (3 + 2√2) / (3)² - (2√2)²

m = (3 + 2√2)/(9 - 8)

m = (3 + 2√2)

इसी प्रकार ,

n = 1/(3 + 2√2) × (3 - 2√2)/(3 - 2√2)

n = (3 - 2√2) / (3)² - (2√2)²

n = (3 - 2√2) / (9 - 8)

n = (3 - 2√2)

(i) m² = (3 + 2√2)²

= (3)² + (2√2)² + 2(3)(2√2)

= 9 + 8 + 12√2

= 17 + 12√2

(ii) n² = (3 - 2√2)²

= (3)² + (2√2)² - 2(3)(2√2)

= 9 + 8 - 12√2

= 17 - 12√2

(iii) mn = (3 + 2√2) * (3 - 2√2)

= (3)² - (2√2)²

= 9 - 8

= 1
