1.8014399e+16

Explanation:

So before you can divide the numbers you have to simplify the exponents. You probably learned P(parentheses) E(exponents) M(multiply) D(divide) A(add) S(subtract.

  • PEMDAS is important because it shows you what order to so something in.
  • Exponents is before divide so you simplify the exponents and you get 8^15= 3.5184372e+13 and 8^-3 = 0.001953125.
  • So after you simplify the exponents you can now divide them
  • Now (3.5184372e+13) ÷ (0.001953125) = 1.8014399e+16

8^15 ÷ 1/8^3 = 8^15 x 8^3=8^18
