(112)*(5^4)=(2*2*2*2*7)*(5*5*5*5).
=(2*5)*(2*5)*(2*5)*(2*5)*7,
=10*10*10*10*7,
=1000*7,
=70000(ans).

In simple Method we can solve this problem Like:

5 to the power of 4 means 5*5*5*5 = 625.
You can (112*5^4),
= 112*(5*5*5*5),
= 112*(625),
= 70000.

How 2^4 came? Please explain it clearly.

How to put 10/2? Explain.

Why you keep 10÷2?

Thanks @Santhi

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

Thanks for all the given methods.

112*5^4=112*(10/2)^4
= 2*56*(10^4)/(2^4)

2 * 2 * 28 * 10^4
-------------------
2^4

2 * 2 * 2 * 14 * (10 * 10 * 10 * 10)
--------------------------------
2 * 2 * 2 * 2

2 * 2 * 2* 2 * 7 * 10 * 10 * 10 * 10
-----------------------------------
2 * 2 * 2 * 2

Then simply remove the number which is above and below the " ------------" bar
to simply the fraction till any above's number will not repeat( present ) below
thus, we get:
112 * 5^4 = 7 * 10 * 10 * 10 * 10 = 7 0 0 0 0.

That's all!

It is very simple method.
= 112 x 5 x 4,
= 112 x 625,
= 70000.
