I stand by my answer of 15p^5t^2
If that answer is not one the choices, they are wrong.
To get the answer to the expression 5p^2t x 3p^3t, you need to remember two rules of exponents:
1. When you multiply two variables with the same base, you add their exponents. In this case, we have p^2t and p^3t. Since both have the same base (p), we can add their exponents: 2 + 3 = 5.
2. When you multiply two numbers with the same base but different exponents, you multiply the numbers and keep the base. So, 5p^2t multiplied by 3p^3t can be simplified as (5 x 3) times (p^2t x p^3t).
Applying these rules, we get:
(5 x 3) x (p^2t x p^3t)
= 15 x p^(2+3)t
= 15p^5t
Therefore, the final answer is 15p^5t.
