I also thought it was 6 but I use this web sight to taech myself,and 7 was the answer I was given. I know how to use 4x^2, but I would rather use

4x2 meaning 4x times 2 is different than 4x squared by 2. I just wanted to know which font I would use to make a small 2 above the x.(Giggle) - Jan 20th 2009, 08:34 AMLeona_Marie
