2^4*7*5^4
=(10)^4*7
=10000*7
=70000
=(10)^4*7
=10000*7
=70000

5X5X5X5=625 SO 625X112=70000

Another easy method
112=7*2^4
we have to multiply 112 with 5^4
so the solution =7*2^4*5^4=7*(2*5)^4=7*10^4=70000
This is the answer.
112=7*2^4
we have to multiply 112 with 5^4
so the solution =7*2^4*5^4=7*(2*5)^4=7*10^4=70000
This is the answer.

Another most easy method
5x5x5x5=650 so 625x112=70000
this is the answer.
5x5x5x5=650 so 625x112=70000
this is the answer.

(112x5^4) = (112x625)
= 112 (600+25)
= (112x600+112x25)
= 67200+2800
= 70000.
= 112 (600+25)
= (112x600+112x25)
= 67200+2800
= 70000.

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

We can also use simple method by using multiplication.
i.e.,
5^4=5*5*5*5=625.
Then,
112*625=70000.
i.e.,
5^4=5*5*5*5=625.
Then,
112*625=70000.
