Question

Helpp
multiply with monomial

Answer 1

The answer is B

Explanation:

You can multiply it using Indices formula, a^m × a^n = a^(m+n) :

(-4y)(-9y⁹)

= (-4×-9)(y×y⁹)

= 36y^(1+9)

= 36y^10

Answer 2

Explanation: To simplify this problem, we can first multiply our coefficients hut we must add the exponents on the like bases.

This idea is called the product rule.

So we have -4 · -9 which is 36.

Now add the exponents.

Think of the
`y` as
`y^1`.

So we add our exponents to get
`y^(10)`.

So our answer is
`36 y^(10)`.
