Evaluate each of the following variable expressions. Assume that r=-2, s= -1, t=3, u=-6, and v=10.

Question

1. vu/rst
2. rtv/su
3. r^3/s^3
4. r^2/u
5.uv^2/r^3
6. su^2/t^2

Answer 1

Just substitute and evaluate.
I will do the first, you do the rest

1. vu/(rst) , I will assume that is what you meant.
= (-6)(10)/( (-2)(-1)(3) )
= -60/6
= -10
