Understanding the Problem

When dealing with square roots, it's essential to simplify the expression by factoring out any perfect squares. In this case, we have the expression $\sqrt{100 x^7}$, and our goal is to simplify it.

Breaking Down the Expression

To simplify the expression, we need to break it down into its prime factors. We can start by factoring out the perfect square from the expression.

$\sqrt{100 x^7} = \sqrt{100} \cdot \sqrt{x^7}$

Simplifying the Square Root of 100

The square root of 100 is a perfect square, which is equal to 10.

$\sqrt{100} = 10$

Simplifying the Square Root of $x^7$

The square root of $x^7$ can be simplified by using the property of square roots that states $\sqrt{a^n} = a^{n/2}$. In this case, we have $n = 7$, so we can simplify the expression as follows:

$\sqrt{x^7} = x^{7/2} = x^{3.5}$

Combining the Simplified Expressions

Now that we have simplified the square root of 100 and the square root of $x^7$, we can combine the two expressions to get the final simplified expression.

$\sqrt{100 x^7} = 10 \cdot x^{3.5}$

Conclusion
