Since the first wasn't awnsered .
3⁵.3-¹=

729

Step-by-step explanation:

When two terms have the same base (in this case 3) you can just add the exponents so this could become and if you need to simplify, its 3*3*3*3*3*3 or 729

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.
