Our author says easiest way.
Ex: Any no which is multiply by multiples of 5 we can follow these method.
= 187*5= 1870/2 = 935.
i.e, 5^1 = 5. So one zero.
If 125 means 5^3 = 125, so 000 to be added.
How many zero to be added in numerator that much of 2 to be added in denominator?
If 625 means in 1870000/2*2*2*2.

112*5^4.
= 28*4*5*5*5*5.
= 14*2*2*2*5*5*5*5.
= 7*2*2*2*2*5*5*5*5.
= 70000.
= 28*4*5*5*5*5.
= 14*2*2*2*5*5*5*5.
= 7*2*2*2*2*5*5*5*5.
= 70000.

= 112 (5*5*5*5).
= 112*625 = 70000.
= 112*625 = 70000.

112*5^4 = (100+12)*625.
= (100*625)+(12*625).
= 62500+7500.
= 70000.
= (100*625)+(12*625).
= 62500+7500.
= 70000.

= 112*(5*5*5*5).
= 112*(25*25).
= 112*(625).
= 7000.
= 112*(25*25).
= 112*(625).
= 7000.

In simple Method we can solve this problem Like:
5 to the power of 4 means 5*5*5*5 = 625.
625*112 = 70000.
5 to the power of 4 means 5*5*5*5 = 625.
625*112 = 70000.
