$sqrt 4 xx sqrt 4 =4$
A Square and a square root are inverse operations and cancel each other out.

Each operation has an inverse. One does, the other undoes.

$+6 -6 =0$

$8 xx 3 div 3 = 8$

$sqrtx^2 = x$

In this case we have two possible methods

$sqrt 4 xx sqrt 4 = sqrt16 =4$

OR $(sqrt4)^2$ = 4
