Answer 2

Answer:

The last digits are 0,9

Step-by-step explanation:

For numbers ending with 5, its pretty straight forward

If your power is even, then your last 2 digits are always 25

And if the power is odd, then look at your 10s digit.

If the 10s digit is odd, then last 2 digits are 75

If the 10s digit is even, then last 2 digits are 25
