Question

solve v and vi please​

Answer 1

Answer:

v) (3√2 + 1) /(2√5-1)

= (3√2 + 1)(2√5+1)/(2√5-1)(2√5+1)

= 6√10 + 3√2 + 2√5 + 1/ (2√5)² -(1)²

= 6√10 + 3√2 + 2√5 + 1 / 19(Ans)

vi) 3√2 + 2√3/ 3√2 - 2√3

= (3√2 + 2√3)(3√2 + 2√3)/(3√2 - 2√3)(3√2+2√3)

= (3√2 + 2√3)² / (3√2)² - (2√3)²

= (3√2)² + 2×3√2×2√3 + (2√3)² / 18-12

= 18 + 12√6 + 12 /6

= 6(3+ 2√6 + 2)/6

= 3+2√6 + 2(Ans)
