112*5^4.
= 16*7*5*5*5*5,
= (4*5)*(4*5)*5*5*7,
= (20*5)*(20*5)*7,
= 100*100*7,
= 70000.
= 16*7*5*5*5*5,
= (4*5)*(4*5)*5*5*7,
= (20*5)*(20*5)*7,
= 100*100*7,
= 70000.

112*5^4=
112=(100+10+2)
5^4=625.
Now
(100+10+2)*625.
=>100*625 +10*625 + 2*625,
=> 62500 + 6250 + 1350,
=> 700000.
112=(100+10+2)
5^4=625.
Now
(100+10+2)*625.
=>100*625 +10*625 + 2*625,
=> 62500 + 6250 + 1350,
=> 700000.

5----2^1,
5*5------2^2=4,
5*5*5------2^3=8,
5*5*5*5-----2^4=16,
Then simply,
112/16=7 and then it is 70000.

Factorise 112 we will get 2^4*7
And 5^4*2^4=we get 4last zero.
So, 70000.
And 5^4*2^4=we get 4last zero.
So, 70000.
