evalute each expression for r=6, s=5, and t=3.... sr, 56? what do i do next? i don't think i can do anything else, pls help me

Answer 1

i think you forgot to type the expression or the function,,
anyway, all you have to do is to substitute the values of r, s, and t (which is r=6, s=5, t=3, and so on..)to the expression and solve it,,

i hope i was able to help,, =)
