Answer 1

Answer:

See your answer is correct.

$you \: have \: seen \: {x}^{2}$

in your question when that

$x = \sqrt{}$

when that square marks goes to rhs then the it changes like × change to ÷,+ change to -, it is possible when the signs from lhs goes to rhs

or signs from rhs comes to lhs.

If you have problem in underoot then see

$\sqrt{25} = 5$

$\sqrt{5 \times 5}$

you can see it is in pair in underoot we have to take one of them out
