 Question 60039: Hello. I really don't understand the whole simplifying radicals thing I learned today in class. I was wondering is you could explain it to me because my classmates couldn't help me. The directions say to express each radical in simplest form. under the radical sign it says 75x12(to the twelfth)y5(to the fifth). one of the other ones says 4 as the index, then under the radical sign 48x3(to the third)y20(to the twentith) if anyone could help me it would me greatly appreciated.Thanks.
