What is the product of -6x3y5 and -4y2? A. -24x3y7 B. -24x3y10 C. 24x3y7 D. 24x3y10
Leto [7]

Answer:

C

Step-by-step explanation:

So we have the product of:

(-6x^3y^5)\cdot(-4y^2)

Multiply. Combine like terms:

=(-6\cdot -4)(x^3)(y^5\cdot y^2)

The first term is 24.

The second term stays as it is.

The third term will equate to y^7. Recall how to multiply exponents. The base stays constant and you add the exponents. Thus:

=24x^3y^7

Our answer is C.

And we're done!
