325 = 847288609443. The last digit is therefore "3".
On your calculator (if you have a scientific calculator; and if you don't but you are using Microsoft Windows you can get a scientific calculator up by going to Start and typing in "calc" in the run/search box) you will have a button that looks like this:
xy (i.e. x to the power of y)
If you type in "3" then press this button and then put in "25" and press equals you should get the above number!

Determine the last digit of 3 to the 400th power?
It is 1.
How many three digits natural numbers are divisible by 4?
The first 3 digit natural number is 100: 100 ÷ 4 = 25 → first 3 digit natural number divisible by 4 is 4 × 25 The last 3 digit natural number is 999: 999 ÷ 4 = 249 r 3 → last 3 digit natural number divisible by 4 is 4 × 249 → number of 3 digit natural numbers divisible by 4 is 249 - 25 + 1 = 225.
What is the units digit of 3 to the 53rd power?
3
What is the units digit of 7 to the 15 power?
Power 2: units digit 9. Multiply by 49 again to get power 4: units digit 1. So every 4th power gives units digit 1. So 16th power has units digit 1, so the previous power, the 15th must have units digit 3.
What is the one's digit of 7 to the 2015th power Explain the steps you took to reach your answer.?
It is a 3. Look at the ones digit of successive powers of 7; this need only be done by considering the multiplication of the ones digit of the previous power of 7 by 7 (as this is the only calculation that affects the ones digit as each successive power of 7 is the previous power multiplied by 7) and taking the result modulus 10 (to extract the new ones digit as any excess over 9 is carried into the tens column): 7¹ → 7 mod 10 = 7 7² → (7×7) mod 10 = 9 7³ → (9×7) mod 10 = 3 7⁴ → (3×7) mod 10 = 1 7⁵ → (1×7) mod 10 = 7 At this point the pattern of the ones digit will obviously repeat the sequence of the four digits {7, 9, 3, 1}. To find the ones digit of any power of 7, take that power modulus 4 use that digit from the four digit sequence. Note that when taking the number modulus 4, the result will be in the range 0-3; when the result is 0, use the 4th digit from the sequence. 2015 mod 4 = 3 → the third digit of {7, 9, 3, 1}, which is 3, will be the ones digit of 7²⁰¹⁵.

What is the unit digit of 43 to the power of 34 factorial?
The last digit is 3. If you multiply 3 repeatedly by itself, you get the last digits:3, 9, 7, 1, 3, 9, 7, 1... In other words, every fourth power of 3 will end with the digit 1. Since any factorial starting at 4! has 4 as a factor, it follows that the last digit is 1.

What is the 2 digit country code plus 25?
There is no 2-digit country code +25. It does not exist. With the exception of +20 (Egypt) and +27 (South Africa), all country codes beginning with +2 are 3-digit codes. There are several 3-digit country codes that begin with +25.
