Question

Find the product. y 4 · y 5

Answer 1

y^4 · y^5 =y^9

---------------------------

Answer 2

Answer:
`y^9`

Explanation:

The product law of exponent says that for any arbitrary number a, we have:

`a^m* a^n=a^(m+n)`, where powers m and n are any number.

The given expression:
`y^4\cdot y^5`

Using product law of exponents , we get

`y^4\cdot y^5\\\\=y^(4+5)\\\\=y^9`

Hence, the simplified expression of the given expression is
`y^9`.
