Question

Rewrite the expression in the form y^n

y^-4 * y^3

Answer 1

When you multiply and the bases are the same you add the exponents together.
-4+3=-1

So the answer is y^-1

Answer 2

Since the base is the same and they are multiplying, write one base and add the exponents.



`{y}^( - 4) * {y}^(3) = {y}^( - 4 + 3)`

`= {y}^( - 1)`
