## What is a unit digit pattern?

When any number is raised to the power n, where n = 1, 2, 3…, its units digit follows a pattern or a cycle. For example, 2 1, 2 2 , 2 3, 2 4… and so on end with 2, 4, 8, 6, 2, 4, 8, 6, 2, 4… In this case the units digit repeats after every 4 powers.

## What is the unit digit of 2323 !?

For the numbers ended with 3 we use 4 pattern ,i.e for 23^23^23 divide the last power by 4 and find out the remainder ,if the reminder is 3 we get 7 in unit place (23^23^3 = 23^xxxx7) again divide the power by 4 we got 3 in unit place in the reminder (23^xxx3 = xxxx7) so 7 is the digit in unit place.

What is the unit digit of 57 45?

7

### What is the units digit of 33 408?

The pattern in the units digit is 3, 9, 7, 1, 3, 9, . . . . The pattern will continue to repeat with every four integers of the exponent. Dividing 408 by 4 yields 102 with no remainder. Therefore, the units digit of 33408 will be the same as the units digit of 334, which is 1.

### What is the units digit of 333333?

9
The pattern repeats every four digits. Imagine that you complete this table to 58 rows. 58/4 = 14 with a REMAINDER 2 so the pattern repeats 14 times and then there are two more rows with 3 and 9 in the units digit column. Thus the units digit of 358 is 9….
