Question

$\sqrt{a + b} = 17 \: and \sqrt{a - b} = 1 \: \: then \: \sqrt{ab} \: =$
​

Answer 1

$here \: is \: your \: answer \:$

$\sqrt{a} + \sqrt{b} = 17 \\ \\ \sqrt{a} - \sqrt{b} = \: 1 \\ \\ \sqrt{a} = 9 \: and \: \sqrt{b } = 8 \\ \\ \sqrt{a} \sqrt{b} = \sqrt{ab} \\ \\ therefore \: 9 \times 8 = 72$

$hope \: it \: is \: helpful \: for \: you..$ ✅✔✔
