Question

Can we have any n e N, where 7" ends with the digit zero?​

Answer 1

HEY MATE UR ANSWER IS BELOW
SINCE 7 IS PRIME NO. ITS FACTOROZATION IS (7 x 1) ONLY


SO IT CAN NOT BE WRITTEN IN FORM OF 2 x 5 so for any value of n 7^n can not be end with zero

Answer 2

Answer:

Step-by-step explanation:

Let's assume 7^n ends then it must be divide by 5 i.e. it's prime factorization must contain 5 but 7 is a prime and do not contains 5 hence fir for any n€N 7^n will not emd with a 0.
