Question

Simplify
5^3 / 5 ^7
leaving your answer in index form

Answer 1

Answer: The answer is 0.0016 Or 1/625

Explanation:

First step you Simplify 5^3 and 5^7 which is going to look like this:

5^3 = 5x5x5 = 25x5 = 125

and

5^7= 5x5x5x5x5x5x5=25x5x5x5x5x5= 125x5x5x5x5= 625x5x5x5=3125x5x5=15625x5= 78125

then divide 125 with 781225

you will get 0.000160005 but you would take out what goes after 16 and it would just have to grab 0.00016 and done

Answer 2
