It wouldn't be if I could figure out what the hell you're calculating the root of. The first calculation basically seems to be 1755^18/9. Unless you mean ^(18/9) the number would become ridiculously large. If you're rooting the entire thing, it'd be the square root of -45, which is impossible with real numbers. If you're rooting -51 we run into the same problem. Taking the square root of either numbers in the second calculation is meh since they don't give integers. Taking the square root of the entire thing works for the first part but the second one is a negative number. There's also a missing parenthesis somewhere in there.
