1.)
(x/x+6)(6/x6)=(x^2+36)/(x^236)
2.)
(r2)(2r)=0
3.) add
(8/ty^2)+(9/t^2y)
4.)add
(7/w)+(8/w^2)
5.)add
((r+10)/r)+(r/(r+10))
6.) divide
((z^21)/16z+16) / ((z1)/4)
7.) find LCM
11(t7) and 77(t7)
8.) remove factors of 1
w^29 / 3w
9.) divide and simplify
((d+2)/(d4))/((8d+16)/(d5))
I know that there are alot of questions but these are the one's that for some reason i just cant get to work out.
