This looks really hard but when you break it up. And simply the exponents it is a way easier
5 to the power of 10 is 9,765,625
5 to the power of 2 is 25
So 9,765,625/25 = 390,625
And 390,625 is equal to 5 to the power of 8
So your explanation is that you have to simply the exponents and then you divide the top by the bottom and you get an answer, that can be simplified in exponents which is 5 to power of 8
Hope that helps
