Simplify

(x^3 y^5) (x^8 y^10)

When multiplying two exponentials with the same base, you add the exponents. Thus,

(x^3 y^5) (x^8 y^10) = x^(3+8) y^(5+10) = x^11 y^15

To simplify the expression (x^3 y^5)(x^8 y^10), you can follow the rules of exponents. When multiplying two terms with the same base, you add the exponents.

Let's simplify the expression step by step:

(x^3 y^5)(x^8 y^10) = x^(3+8) * y^(5+10)

Simplifying the exponents:

= x^11 * y^15

So, the simplified expression is x^11 * y^15.
