Posted by Jessie on Monday, October 18, 2010 at 3:48pm. I think I figured it out-please check
I'm really stuck on these problems-
Simplify 6xy(3xy)^-2? I think this is 2/3xy
choices were
2/xy
3xy
2xy
2/3xy
Simplify 12xyz^-2/8x^-2z
choices were 3x^2y/2z^3
3x^3y/z^3
3x^3y/2z^3
x^3/2z^3
I think it is 3x^3y/2z^3
Thank you for checking
Thank you
