**How to find last two or three digits of a large exponent**

26/06/2007Â Â· That means that 3^6 in the octal system has four digits, which we can see with the expansion of the number: 3^6 = 1*(8^3) + 3*(8^2) + 3*(8^1) + 1*(8^0) = 1331(base 8) (2) Now we will answer your question: find a number with 500 digits in the octal system when put to the 1000th power and find its octal and decimal representation. If a number has 500 digits in the octal system and it is â€¦... I. When the number â€˜aâ€™ ends in 1 Suppose we want to find the last two digits of the expression \(111^{2556}\). This means â€˜aâ€™ = 111 and â€˜bâ€™= 2556.

**If X Y denotes X raised to the power of Y find out last**

Detailed Solution. The last two digits of 7 1 are 07. The last two digits of 7 2 are 49. The last two digits of 7 3 are 43. The last two digits of 7 4 are 01....From the 16th power onwards the numbers formed by the tens and units digit are 56, 52, 84, 28 and then repeat. I want the tens and units digits of $73142^{93}.$ I now see that after the first 15 powers I have $93 - 15 = 78$ rows remaining in my table.

**What is the last digit of 3^100? Physics Forums**

Take last two digit 41 from 1941 and raise it to the unit digit power 3 from 3843. (i.e) 41^3 = 68921. From this take only the last two digit 21. (i.e) 41^3 = 68921. From this take only the last two digit 21. how to find your lost kitten 30/01/2015Â Â· Best Answer: Remember 1 raised to any power will give 1 as unit digit. To find the digit in the 10th place, we have to multiply, 10th digit in the base x unit digit in the power. So the Last two digits of the given expression = 21 + 61 = 82.

## How To Find Last Two Digits Of A Power

### We know that a number is divisible by 4 if the number formed the last two digits is divisible by 4. 00/4 = 0 that means remainder is ZERO and we know that in case of 7 ,the cycle is 4 so we will find out the 4 th power of 7 7 4 if you still find difficult, let us simplify it 7 4 = 7 2 Ã— 7 2 = 9 Ã— 9 (Unit digits) = 81 Unit digit so the last digit in the 7 45304000 is 1 From the table we also

- A number is divisible by 25 if the number formed by its last two digits is divisible by 25. Similarly, 2 3 = 8 and 5 3 = 125 are factors of 1000, so A number is divisible by 8 if the number formed by its last three digits is divisible by 8.
- We know that a number is divisible by 4 if the number formed the last two digits is divisible by 4. 00/4 = 0 that means remainder is ZERO and we know that in case of 7 ,the cycle is 4 so we will find out the 4 th power of 7 7 4 if you still find difficult, let us simplify it 7 4 = 7 2 Ã— 7 2 = 9 Ã— 9 (Unit digits) = 81 Unit digit so the last digit in the 7 45304000 is 1 From the table we also
