Question

(3527)654 में इकाई अंक क्या होगा?​

Answer 1

Given that,

A number i.e. $(3527)^{654}$.

To find,

The unit place of the given number

Solution,

The unit place of 3527 is 7 and it is repeated 654 times. It means that we can write it as : $p=7^{654}$. We know that the repeated places are as follows :

$7^1=7\\\\7^2=9\\\\7^3=3\\\\7^4=1\\\\7^5=7$

When 654 is divided by 4, the remainder is 2. So,

$p=7^{654}=7^{4n+2}$, n is remainder

It means that the unit place of q is 9. Hence, the unit place of $(3527)^{654}$ is 9. Hence, this is the required solution.
