My thoughts exactly, muneepenee!

This cannot be evaluated if sqrt(abc) is included in the expression because it would imply sqrt(-120). However, if ^3 followed by square root is meant to represent cube root of -120, this would lead to taking the log of a negative number which is also not possible. If the expression includes sqrt(a)*b*c the negative b precludes evaluation of the log.
