Question
are these correct now i hope?
Problem #1
simplify
(m^2)/(8) divided by (m^5)/(16)
My answer: (2)/(m^4)
Problem #2
multiply
(3x-30)/(x^2-4x) times (8x)/(10-x)
My answer: (-6)/(x)
No. 2/m^3
(3x-30)/(x^2-4x)* (8x)/(10-x)
3*(x-10)*8x /(x-10)(-1)(x)(x-4)
x's divid out, the (x-10) divides out
3*8/(-1)(x-4)
and reduce. Check this.
