Question

srivalika said that (√a+√b)^2=√a+2√ab+√b. will you agree with her. explain

Answer 1

$\textbf{ Hello Mate! }$

${(x + y)}^{2} = {x}^{2} + {y}^{2} + 2xy$

Similarily,

${( \sqrt{a} + \sqrt{b} )}^{2} \\ = { \sqrt{a} }^{2} + { \sqrt{b} }^{2} + 2 \sqrt{a} \sqrt{b} \\ = a + b + 2 \sqrt{ab}$

Hence, we $\textbf{ disagree }$ with Srivalikas answer because she might have forgotten that root symbol with square cancells and get 1.

Thus, her answer is wrong.

Hope my answer helped.

Have great future ahead!
