Question

Find the product. y 4 · y 5

Answer 1

Answer: $y^9$

Step-by-step explanation:

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

$a^m\times a^n=a^{m+n}$, 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 $y^9$.

Answer 2

 y^4 · y^5 =y^9
