**Question:**

12. Which is not correct in the exponential value?

**Options:**

a. \(2^4 = 16\)  
b. \(16^{1/2} = 4\)  
c. \(4^2 = 16\)  
d. \(16 = 1/2^4\)  

**Explanation:**

- **Option a**: \(2^4 = 16\) is correct because \(2 \times 2 \times 2 \times 2 = 16\).
- **Option b**: \(16^{1/2} = 4\) is correct because \(\sqrt{16} = 4\).
- **Option c**: \(4^2 = 16\) is correct because \(4 \times 4 = 16\).
- **Option d**: \(16 = 1/2^4\) is incorrect because \(2^4 = 16\) does not equal its reciprocal \(\frac{1}{2^4} = \frac{1}{16}\).

Therefore, the incorrect statement is **d**.
