Can someone help me?
'Which is the last digit of the total 2015 to the power of 2 + 2015 to the power of 0 + 2015 to the power of 1 + 2015 to the power of 5?'
Unfortunately, you can't write exponents to my laptop.
But if you have a laptop, you can type it into the calculator.
2015 ^ 0 = 1.
The other potencies from 2015 always result in a number with the number 5 at the end because of the 5 at the end.
So you have three numbers with a 5 at the end, the sum of which results in a number with a final digit of 5, to which the 1 is added. This is how you get to the last digit 6.
You don't need a computer for this.
You shouldn't use the laptop either, but think.
You shouldn't calculate the numerical value of the sum, only the final digit.
Note: The sum of several numbers, each ending with a 5, is either zero or five and 2015 ^ 0 = 1.
You should do the rest yourself.
The boy shouldn't learn to use the laptop, he should learn to think.
2015² + 2015⁰ + 2015¹ + 2015⁵
2015² + 1 + 2015 + 2015⁵
You only need the last digit.
So:
2015² -> last digit becomes 5.
+1 = 6
+ (201) 5 = 11 so 1.
+ (201) 5⁵ -> 5⁵ = 3125 -> 5 so 1 + 5 = 6
The last digit is 6.
Thanks for your rating, but now I'm getting cheeky too. I found your answer too detailed. Only what you have to work for yourself can be used later as a skill. So it's too convenient.

My brief research resulted in:

That's how it is.
