12e^5 ÷ 3e^3
= (12/3) * e^(5 - 3)
= 4e^2
-----------------------
a) a^5 ÷ a^3
= a^(5 - 3)
= a^2
-------------------
b)
c^4
---------- = c^(4-3) = c^1 = c
c^3
----------------
expanding the following, using the distributive property to expand those below
a) 2(x+3) = 2x + 6
b) 5(2x - 4) = 10x - 20
c) 4(2x + 1) = 8x + 4
d) 6(x - 4y) = 6x - 24y
