Problem Solving (PS) | Re: How many multiples of 4 lie between 4^4 and 4^5, inclusive?

Given range is
4^5-4^4
= 4^4 (4-1)

Now to find out the multiples of 4 we need to divide 4^4*3 by 4

Therefore, 4^3*3 =64*3= 192.

Since the question says its inclusive therefore we need to add +1.

Total number is 192+1=193

To further clarify inclusive formula :

How many numbers from 1 to 10 inclusive?

It is: (10-1)+1 =10
