Question

I need a little help because i forgot how to do this



simplify. y^2y^3​

Answer 1

It is 3y^3 bc u take all the matching letters and add them up together

Answer 2

`y^(5)`

Explanation:

Using the rule of exponents

`a^(m)` ×
`a^(n)` ⇔
`a^((m+n))`

Hence

`y^(2)` ×
`y^(3)` =
`y^((2+3))` =
`y^(5)`
