Use the product rule to simplify the expression: 5 to the 10th power×5 to the3rd power
To simplify the expression using the product rule, we add the exponents when multiplying numbers with the same base.
5^10 * 5^3 = 5^(10+3) = 5^13
So, 5 to the 10th power times 5 to the 3rd power is equal to 5 to the 13th power.
