If b varies directly as the square root of w and b equals a negative 24 when w equals 36, what is w when b is equal to 1/8?

" b varies directly as the square root of w" > b = k√w, where k is a constant
given: b = 24 , w = 36
24 = k√36
k = 24/6 = 4
b = 4√w
1/8 = 4√w
√w = 1/32
by definition √w will be a positive number , so there is no solution.
Are you sure b wasn't 1/8 ?
