Answer 1

Answer:

hope u get this well

Step-by-step explanation:

it is a+b_/2 instead of a-b_/2

thnxx

Answer 2

$\implies \: \frac{5 \sqrt{2} + 3 }{5 \sqrt{2} - 7} = a - b \sqrt{2} \\ \implies \: \frac{5 \sqrt{2} + 3 }{5 \sqrt{2} - 7} \times \frac{5 \sqrt{2} + 7 }{5 \sqrt{2} + 7} = a - b \sqrt{2} \\ \implies \frac{50 + 35 \sqrt{2} + 15 \sqrt{2} + 21 }{50 - 49} = a - b \sqrt{2} \\ \implies \: 71 + 50 \sqrt{2} = a - b \sqrt{2} \\ comparing \: both \: sides \: we \: get \\ a = 71 \: \: \: and \: \: \: b = - 50$
