PLEASE ANSWER FAST.
Can the number 6, n being a natural number, end
with the digit 5? Give reasons.​

Answer 1

Answer:

Step-by-step explanation:

Consider the number 6n , for n a natural number.

A number ending with digit 5, must be divisible by 5.

But 6 x 5 =30.

So 6 multiplied by any multiple of 5 has last digit zero.

so the last digit of 6n can never be 5.
