Question

without actually dividing determine after how many places the decimal from of 125. To the power 4.5 will determine

Answer 1

I HAVE DONE IT IN DETAIL

1) after decimal point there will be 8000 numbers.. as 125/2=62.5 and after each increase in power denominator 10 will also increase leading to adding extra 0 in denominator thus we can get answer..

2) It will be a terminating decimal as there is only 5 in denominator so it will end somewhere after decimal point...
