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

this is a law of exponents problem as. Anything with common bases and being  multiplied, have the exponent law of adding the exponents. Let's break this problem apart accordingly.

First the x's

-x * x^3

-x^(1+3)

-x^4

Now the y's

y^7 * y

y^(7+1)

y^8.

Now multiply the two variables by 7

7(-x^4y^8)

-7x^4y^8

Thus this is your final answer. -7x^4y^8
