Question

If √2= 1.414 then find the value of √8+√50+√72+√98

Answer 1

Hey mate

$\sqrt{8} + \sqrt{50} + \sqrt{72} + \sqrt{98} \\ = 2 \sqrt{2} + 5 \sqrt{2} + 6 \sqrt{2} + 7 \sqrt{2} \\ = \sqrt{2} (2 + 5 + 6 + 7) \\ = \sqrt{2} \times 20 \\ = 20 \times 1.414 \\ = 28.240 \: ans$

Answer 2

we first make the factors of root it gives the answer 2root 20 than final answer is 28.28
