what is the product of -8x^2y and -2xy^3 using the laws of exponents??

• math -

Multiply the coefficients (numbers in front).
for the letters with exponents. You keep the letter and you add the exponents.

Remember that y is y^1

Try it and I will check it for you.

• math -

-16x^2y^2x^3y^3??

• math -

(-8)(-2) that takes care of the coefficents = 16

(x^2)*(x^1) = x^3

(y^1)(y^3) = y^4

Now, put them all together and you will have the answer.

• math -

so 16x^3y^4

thank you !

• math -

Yes. that is it. I hope it makes sense to you.

• math -

It really does thank you. and quick questions do you do tutoring lessons??

• math -

Sorry, I don't. I am on her quite often.
