Going over some concepts I'm not fully understanding. This one deals with fractional exponents. Evaluate each, if possible: 1.) (32)^3/5 2.) 4th root of ((30pq)^7) >(the 7 is inside the radical) For 1.), I'm not sure if there is a simple way to reduce it. I tried figuring out and kept running into Newton's Method, which seems kind of relevant, but there has to be an easier way to simplify this. I started doing it this way, which is really long and easy to make a mistake, but it's the only way I can visualize it right now: 5th root of ((32)^3) I factored the large number and ended up with (2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2) so 2^11, since we're taking the 5th root, I removed 10 of the 2's in the radical, and I was left with: 4 times the 5th root (2). I'm probably way off, I don't know. I can't figure an easier way to do this. For the 2nd problem, I have no idea. It's just too hard for me to simplify doing it this way, if that last way was even correct.
