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

Very simple method for :
= 112 * 5^4,
= 112 * (5 * 5 * 5 * 5),
= 112 * 625,
= 70000.

Thanks for all methods.

Thanks for all your solution and explanation.

Thanks for all methods and explanations.

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

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!

Thanks for all the given methods.

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