Question

what can you say about B if the following statement is true (sqrt B)^2=BA. B must be the whole number B. B must be the negative valueC. B must be a non positive valueB. b must be a non negative value

Answer 1

non-negative

1) Considering that this expression yields the following:

$\begin{gathered} (\sqrt[]{b})^2= \\ \sqrt[]{b^2}=b \\ \end{gathered}$

2) Then we can state that the b must be a non-negative value since the square root does not admit a negative number, otherwise, it would cause an undefinition.

3) Hence, the answer is D)b must be a non negative value
