# For what value of ‘K’ in 7n=K, ‘n’ will be a Natural number?

**Answer: (4) 2401 **

**Solution:-**

7^n = K

The value of K will be multiple of 7 and only option (4) 2401 is multiple of 7.

Then factors of 2401 = 7 x 7 x 7 x 7

= 7^4

7^4 = 2401

Then the value of K is 2401.

Hence, the correct answer is option (4) 2401.
