To solve the expression √8 + 5, let's break it down step-by-step:

1. First, we need to simplify the square root of 8 (√8). The square root of 8 can be written as the square root of 4 multiplied by the square root of 2 (√4 * √2).
√8 = √4 * √2

2. The square root of 4 (√4) is equal to 2.
√4 = 2

3. Now, let's substitute the values back into the original expression: √8 + 5 = 2 * √2 + 5

So, the simplified form of √8 + 5 is 2√2 + 5.

To find the value of √8+5, we need to evaluate each term separately and then add them together.

First, let's find the value of √8. The symbol √ denotes the square root. √8 means "the square root of 8." The square root of a number is a value that, when multiplied by itself, gives the original number.

In this case, we need to find a number (let's call it x) that satisfies the equation x * x = 8. By solving this equation, we'll find the value of x, which is the square root of 8.

To solve x * x = 8, we take the square root of both sides of the equation:

√(x * x) = √8

This simplifies to:

x = √8

Now, let's evaluate the square root of 8. We can recognize that 8 can be expressed as the product of 4 and 2 (i.e., 4 * 2 = 8). Since 4 is a perfect square (2 * 2 = 4), we can take its square root:

√4 = 2

Therefore, the value of √8 is 2√2.

Now, let's substitute this value back into the original expression:

√8 + 5 = 2√2 + 5

Since this expression cannot be simplified further, the final answer is 2√2 + 5.
