I. `x^(2)=16`
II. `y=sqrt(16)`

Options

A. `xley`
B. `xlty`
C. `xgey`
D. `xgty`

Answer

To solve the given equations step by step, let's break them down:

### Step 1: Solve the equation \( x^2 = 16 \)

To find the value of \( x \), we need to take the square root of both sides of the equation.

\[ x^2 = 16 \]

Taking the square root of both sides gives us:

\[ x = \pm \sqrt{16} \]

### Step 2: Calculate \( \sqrt{16} \)

Now, we calculate the square root of 16:

\[ \sqrt{16} = 4 \]

### Step 3: Write the final values for \( x \)

From the previous steps, we have:

\[ x = \pm 4 \]

This means \( x \) can be either 4 or -4.

### Step 4: Solve for \( y \)

Now, we need to find the value of \( y \) given by the equation:

\[ y = \sqrt{16} \]

### Step 5: Calculate \( y \)

Since we already calculated \( \sqrt{16} \) in Step 2, we know:

\[ y = 4 \]

### Summary of Results

- The values of \( x \) are \( 4 \) and \( -4 \).
- The value of \( y \) is \( 4 \).
