The result of (2xy^3)(9x^2y^5)
For (8a)(2a^3b)(0) as one of the terms is 0, the result is 0.
The required products are (2xy^3)(9x^2y^5) = 18*x^3*y^8 and (8a)(2a^3b)(0) = 0

A)Using the following exponential law yields:
`a^x*a^y = a^(x+y)`
Reasoning by analogy, yields:
`(2*x*y^3)*(9*x^2*y^5) = (2*9)*(x^(1+2))*(y^(3+5))`
`(2*x*y^3)*(9*x^2*y^5) = 18*x^3*y^8`
B) Since one factor is 0,you need to use zero product rule, such that:
`(8a)(2a^3b)(0) = 0`
Hence, evaluating the multiplications, yields `A) `
`18*x^3*y^8, B) 0. `
