Simplify the expression a² • 3a and explain your steps pls

3a^3

Step-by-step explanation:

Ok I got you bud now the the first thing to notice that they're all the same variable. so the way I learned to look at is like this  

1a^2 x 3a^1

so the reason I put it like this is so I remember that in front of every variable is a coefficient. so you would first multiply the coefficient

3x1=3

3

then multiply the a's you have one a that is being squared and one a to the first power so since your multiplying them you just add the exponents

a^1 + a^2 = a^3

so when you put it all together it says 3a^3

hope this helps

correct
