Question

8 Check whether 12" can end with the digit O or 5, for
any natural number n. NCERT Exemplar; CBSE 2015​

Answer 1

Answer: It cannot end with zero or five.

Step-by-step explanation:

it cannot end with zero or five.

because,

here ,the number is 12^n.where n is called natural number.

Now , if 12^n is to end with zero,it should have 2 and also 5 in its prime factors to end with zero.it needs at least a single multiple of 5 or any number  in its prime factors.so 12^n cannot end with zero for any natural number.

It has only 2 as a factor and there is no number from which multiplying 2 we can get 5 at the end. So it cannot end with digit five.
