112*5^4 = 112*25*25.
625(112) = 625(100+12).
62500+7500 = 70000.

This is a normal calculation.

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

5*5*5*5 = 625.
625*112 = 70000.

That is it.

(100+10+2)(5^2)(5^2).

(100+10+2)25^2.

(100*625+10*625+2*625).

62500+6250+1250.

70000.

Hi @Ritesh, Its simple man: your Q: 10/2.

You can divide this number 10/2 you will get answer 5.

We just take that form (10/2) for our convenient. Moreover you can take also 50/2 if you take, would be 25. That's all buddy.

(100+12) (5*5*5*5).
(100+12) (625) .

100*625 = 62500 + 12*625 = 7500.

Answer = 70000.

I did not multiply these numbers to get the answer. The simplest method is to find the number of zeros. See here we have four 5 and we can have fours 2, which when multiplied will give maximum number of fours zeros. And there is only one option with 4 0's that is 7000. :).

Easiest way is 112*5*5*5*5=70000.

I have used multiplied 5 four times because they have given 5 to the power of 4 hence you can use it in a simplest manner by multiplying 5 four times.
