Answer:
20x^9y^7.
Step-by-step explanation:
(5xy^2) (4x^8y^5)
= 5*4 x*x*8 y^2 *y^5
= 20x^9y^7.
original equation:
[tex](5xy^2)(4x^8y^5)[/tex]
when multiplying exponents, simply add the exponents of like bases.
[tex](5)(4)=20\\\\(x)(x^8)=x^9\\\\(y^2)(y^5)=y^7[/tex]
final answer
[tex](5xy^2)(4x^8y^5)=20x^9y^7[/tex]
