`sqrt(1521)+sqrt(225)=?`

Options

A. 56
B. 58
C. 54
D. 62

Explanation

To solve the expression \( \sqrt{1521} + \sqrt{225} \), we will break it down step by step.

### Step 1: Calculate \( \sqrt{1521} \)
First, we need to find the square root of 1521.

To do this, we can factor 1521 or recognize that:
\[ \sqrt{1521} = 39 \]
This is because \( 39 \times 39 = 1521 \).

### Step 2: Calculate \( \sqrt{225} \)
Next, we find the square root of 225.

Similarly, we can recognize that:
\[ \sqrt{225} = 15 \]
This is because \( 15 \times 15 = 225 \).

### Step 3: Add the results
Now that we have both square roots, we can add them together:
\[ \sqrt{1521} + \sqrt{225} = 39 + 15 \]

### Step 4: Calculate the final result
Now we simply add the two numbers:
\[ 39 + 15 = 54 \]

Thus, the final answer is:
\[ \sqrt{1521} + \sqrt{225} = 54 \]

### Summary of the Solution
The value of \( \sqrt{1521} + \sqrt{225} \) is \( 54 \).
