5 Root 2 Squared: Understanding Calculation and Applications

The expression \(5\sqrt{2}\) squared can be calculated as follows:

\[
(5\sqrt{2})^2 = 5^2 \cdot (\sqrt{2})^2
\]

First, we calculate the square of 5:

• \[ 5^2 = 25 \]

Next, we calculate the square of \(\sqrt{2}\):

• \[ (\sqrt{2})^2 = 2 \]

Now, we multiply these results together:

\[
25 \cdot 2 = 50
\]

Therefore, the value of \((5\sqrt{2})^2\) is 50.

5 Root 2 squared, mathematically represented as \( (5 \sqrt{2})^2 \), refers to the square of the product of 5 and the square root of 2. To calculate this value:

1. Multiply 5 by the square root of 2: \( 5 \times \sqrt{2} \).
2. Square the result obtained in step 1 to find \( (5 \sqrt{2})^2 \).
3. Alternatively, compute \( 5^2 \) and multiply by \( (\sqrt{2})^2 \).

This expression is often simplified in mathematical contexts and has applications in geometry, physics, and engineering where precise calculations involving squares and roots are necessary.

There are several methods to calculate \( (5 \sqrt{2})^2 \):

1. Direct Multiplication and Squaring:
   1. Multiply 5 by the square root of 2: \( 5 \times \sqrt{2} \).
   2. Square the result obtained in step 1 to find \( (5 \sqrt{2})^2 \).
2. Separate Squaring:
   1. Square 5 to get \( 5^2 = 25 \).
   2. Square the square root of 2 to get \( (\sqrt{2})^2 = 2 \).
   3. Multiply the results of steps 1 and 2: \( 25 \times 2 = 50 \).
3. Using Exponent Rules:
   1. Express \( (5 \sqrt{2})^2 \) as \( 5^2 \times (\sqrt{2})^2 \).
   2. Calculate \( 5^2 = 25 \) and \( (\sqrt{2})^2 = 2 \).
   3. Multiply these results: \( 25 \times 2 = 50 \).

These methods provide different approaches to compute the square of 5 times the square root of 2, ensuring accuracy in mathematical calculations involving squares and roots.
