Answer 2

Given:

Consider the given number 4^55

Find:

Last digit of the number

Solution:

Last digit of 4^1 = 4

last digit of 4^2 = 6

last digit of 4^3 = 4

last digit of 4^4 = 6

Here we can observe there are only two last digits 4 and 6

If the power is odd then last digit is 4

If the power is even then last digit is 6

Therefore the last digit of 4^55 is 4.
