​The digit in the unit's place of  $$2^{30}$$​ is: ​​

Correct option is C

Given:

We are to find the unit digit of $$2^{30}$$​​

Concept Used:
The unit digit of powers of 2 follows a cyclic pattern of 4:

​$$\quad 2^2 = 4,\quad 2^3 = 8,\quad 2^4 = 6,\quad 2^5 = 2,\quad \text{and so on...}$$​​

Cycle: 2, 4, 8, 6 → Repeats every 4 terms.

So,  Divide the power by 4 and write the remainder at the place of power. 

Solution:

$$\frac{30}{4}$$ = 2 (Remainder)

Therefore, (2)²= 4

So, the unit digit is 4

Thus, the correct option is (c) 4
