Question

Board exam ka sawal hi plzz
√(x/y) =4 , 1/x + 1/y = 1/xy

Answer 1

Answer:

$\sqrt{ \frac{x}{y} } = 4 \\ \frac{x}{y} = 16 = = = = = = = = 1 \\ \frac{1}{x} + \frac{1}{y} = \frac{1}{xy} \\ \frac{y + x}{xy} = \frac{1}{xy} \\ x + y = 1 = = = = = = 2 \\ from \: eq \: 1 \\ x = 16y \\ so \: putting \: eq \: 1 \: in \: eq \: 2 \\ 16y + y = 1 \\ 17y = 1 \\ y = \frac{1}{17} = = = = = = 3 \\ eq \: 3 \: in \: eq \: 1 \\ x = \frac{16}{17}$

hope it helps.....
