When x=4 and y=2 find the value of :
`x^(2)+2`

Options

A. 18
B. 20
C. 22
D. 24

Answer

To solve the problem, we need to find the value of the expression \( x^2 + 2 \) when \( x = 4 \).

### Step-by-Step Solution:

1. **Substitute the value of \( x \)**:
We know that \( x = 4 \). We will substitute this value into the expression \( x^2 + 2 \).
\[ x^2 + 2 = 4^2 + 2 \]

2. **Calculate \( 4^2 \)**:
Now, we need to calculate \( 4^2 \).
\[ 4^2 = 16 \]

3. **Add 2 to the result**:
Next, we will add 2 to the result we obtained from \( 4^2 \).
\[ 16 + 2 = 18 \]

4. **Final result**:
Therefore, the value of \( x^2 + 2 \) when \( x = 4 \) is:
\[ \text{Value} = 18 \]

### Final Answer:
The value of \( x^2 + 2 \) when \( x = 4 \) is **18**.
