Answer 1

because the last digit is divisible by 5 that number is divisible by 5

Answer 2

Answer:

Step-by-step explanation:

Yes it is divisible by 5

Because value is divisible by only when its last digit will be either 0 or 5

And to solve it

1^11 + 2^11 + 3^11 + 4^11 + 5^11

For finding last digit after solving power...we must didive power by 4 and whatever the remainder we get it must be put as a power over digit ..

Like 11%4 = remainder will be 3

1^3 that means last digit is =1

2^3 that means = 8

3^3 that means = 27

4^3 that means = 64

5^3 that means = 125

We will take only once place digit to simplyfy addition

1+8+7+4+5= 25 or either take its once digit place that is 5

And 5 is divisible 5 therefore

1^11 + 2^11 + 3^11 + 4^11 + 5^11 is divisible by 5 ....
