please help!!!!!

simplify 3^3-8(1+2) over -10-(3+8)

Follow your "order of operations" rules for the numerator to simplify it, then do the same for the denominator. Finally, cancel out any common factors between the numerator and denominator. Can you make an attempt with this information?
 
3^3-8(1+2)over-10-(3+8)=3^3-8(3)over-10-(11)=27-27 over-21 correct!!!!

Wheels,

Good effort -- and on the right track -- just a minor math error to watch out for. 8*3 = 24, so we end up with

(27 - 24)/(-21)
= 3/(-21)
= -1/7

Hope that helps.

(9-3)+3^3 over -5-2(4+1)=6+3^3over -5-2(5)=6+27over-5-10=33over-15

Very well done! One final step, factor both the top and bottom by 3:

33/(-15) = -11/5

PS When you start a new problem, it's best to start a brand new post so everyone (all the other tutors) will look at it.
