One of the ways of finding the units digit of a power is by finding the remainder when that number is divided by Example 3: what is the units digit in the expansion raised to 71?
Example 4: What is the units digit in the expansion of 2 the power of 51? Example 5: The last digit in 6 power is? We hope that you now have a good idea on how to find the units digit of a number raised to power. Here is a small quiz to test your understanding. Start the quiz! I am really interested in knowing what happens to the units. Hi, Anything to zero power is 1. Any number whose units digit ends in 1 or 5, the power of that number will also end in 1 or 5 respectively.
