Simplify the following expression.
12a3865
9a284c5
OA 4ab2
OB. 9ab2
OC. 4a62c
OD. 9ab2c

Answer 1

4ab^2
First, you divide 12 by 3, giving you 4.
Then you divide a^3 by a^2, which is basically just subtracting the exponents, giving you a. Do the same with the rest of the variables. That’s how you get 4ab^2.
