hope this helps, if so hit that thanks button ;D

Explanation:

Answer 2

`21x^7y^8`

Explanation:

`(7x^2y^3)(3x^5y^8)`

we use exponential property to simplify the exponents

`a^m * a^n = a^(m+n)`

`(7x^2y^3)(3x^5y^8)`

`7*3*x^2*x^5*y^3*y^8`

7*3= 21

`x^2*x^5= x^(2+5)=x^7`

`y^3*y^8= y^(3+8)=y^11`

`21x^7y^8`
