**What is the Simplest Form of $\frac{2 \sqrt{2}}{\sqrt{3}-\sqrt{2}}$?**
Understanding the Problem
The given expression is a fraction that involves square roots. To simplify this expression, we need to rationalize the denominator, which means removing the square root from the denominator.
Step 1: Multiply by the Conjugate
To rationalize the denominator, we need to multiply both the numerator and the denominator by the conjugate of the denominator. The conjugate of is .
\frac{2 \sqrt{2}}{\sqrt{3}-\sqrt{2}} \cdot \frac{\sqrt{3}+\sqrt{2}}{\sqrt{3}+\sqrt{2}}
Step 2: Simplify the Expression
Now, we can simplify the expression by multiplying the numerators and the denominators.
\frac{2 \sqrt{2}(\sqrt{3}+\sqrt{2})}{(\sqrt{3}-\sqrt{2})(\sqrt{3}+\sqrt{2})}
Step 3: Use the Difference of Squares Formula
The denominator can be simplified using the difference of squares formula: .
(\sqrt{3}-\sqrt{2})(\sqrt{3}+\sqrt{2}) = \sqrt{3}^2 - \sqrt{2}^2 = 3 - 2 = 1
Step 4: Simplify the Expression
Now, we can simplify the expression by substituting the simplified denominator.
\frac{2 \sqrt{2}(\sqrt{3}+\sqrt{2})}{1} = 2 \sqrt{2}(\sqrt{3}+\sqrt{2})
Step 5: Simplify the Expression Further
We can simplify the expression further by multiplying the terms.
2 \sqrt{2}(\sqrt{3}+\sqrt{2}) = 2 \sqrt{6} + 4
Conclusion
The simplest form of is .
