there are multiple test versions of these:
16r^6s^3/8r^2s^6 answer = B. 2r^4/s^3
(4m^5n^2/m^n)^3 answer = A. 64m^9n^3
cd^4/c^2d^8 answer = C. 1/cd^4
4. It's divided by 2 every time.
I. is false.
II. is true.
III. is false.
Only II. is true, so answer is choice D.
Distribute: - (-3y)
You’ll now get y + 3y
Combine like terms and you’ll get 4y
(I maybe wrong but I think this is probably the answer)
