Question

Find the product. y4 · y3

Answer 1

Because of the way you wrote the problem I am unsure if you meant y^4*y^3 or 4y*3y. So I included the solution to both.

y^4*y^3 = y^7

This is because you add exponents when multiplying them.

If you meant 4y*3y then the answer is as follows:

4y*3y = 12y

Answer 2

The product would be y^7. Remember to use the power of product rule when multiplying exponents.

X^m • X^n = X^m+n.
