hi, I am a little unsure what to head this under, just a quick question (I'm 40 and haven't taken Algebra in years!). The problem is (2ab2)3/(2a3b)2=? (the second 2 and 3 are exponents...on the bottom, the 1st 3 and second 2 are exponents). I answered 2b4/a3. Could someone please tell me if I am rig...
