Solve the formula for the given variable. Assume all variables represent nonnegative numbers.

A=6s^2, for s

A. A/6
B. SQRT A/6
C. -SQRT A/6
D. Not given

I believe the anser is B, but not 100% sure

1 answer

algebraically it would have been ±√(A/6),
but it said all variables are non-negative, so

√(A/6) , the A/6 must be all under the root sign.
