Question

If √2 = 1.414 , √3 = 1.732 and √5 = 2.236 then find values of
1) √98
2) √128 + √48
3) 2√75 - 3√12

plz explain atleast one of the questions ​

Answer 1

Answer:

1. $\sqrt{98} = \sqrt{2 \times 49} = 7 \sqrt{2} \\ = 7 \times 1.414 \\ =$
2. $\sqrt{128} + \sqrt{48} \\ = \sqrt{2 \times 64} + \sqrt{16 \times 3} \\ = 8 \sqrt{2} + 4 \sqrt{3} \\ = 8 \times 1.414 + 4 \times 1.732 \\ =$
