Can someone answer the questions and do what is asks .

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
