How do write 625 in exponential form?

Answer 1

Remember numbers ending in '5' or '0' will divide by '5'

Hence

5)625) = 125

Continue to divide by '5'

5(125) =25

5)25 = 5

5)5 = 1

Remember to keep dividing by a Prime number, '5' in this case, until it is reduced to '1'.

We have divided by '5' four times over.

So 625 in exponential form is 5^(4).

Answer 2

625 in exponential form = 6.25 × 102
