Thank you for the opportunity to help you with your question! Hope your day is going well!

Notice that everything is being multiplied. Therefore by the law of exponents, we are able to add the exponents for common bases. Let's deal with 1 variable at a time.

Step 1: Let's look at the x's

-x * x^2

This is the same as

-x^(1+2)

-x^3

Step 2: Let's look at the y's

y^6 * y

This is the same as

y^(6+1)

y^7.

Therefore we see 4(-x^3y^7). Then you just multiply the four to the whole thing.

-4x^3y^7.

Please let me know if you need any clarification. I'm always happy to answer your questions.

The answer should be -4x^3y^7.


What part were you wrong on?

I multiplied the -4*3, by accident

Ohh! Well, that is incorrect, but it happens. Does everything make sense?
