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
