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

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. 
16x^2y^2x^3y^3??

(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. 
so 16x^3y^4
thank you ! 
Yes. that is it. I hope it makes sense to you.

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