Math Problem Statement
Solution
The expression provided is:
To simplify this, we can proceed by expanding the denominator and then rationalizing the fraction.
Step 1: Expand the Denominator
The denominator is . Using the formula , we have:
Calculating each term:
So, the denominator becomes:
Step 2: Write the Expression
Now, we have:
Step 3: Rationalize the Denominator
To eliminate the imaginary unit from the denominator, we multiply the numerator and the denominator by the complex conjugate of the denominator, which is :
Expanding the denominator:
Now, expand the numerator:
Since :
Step 4: Simplify the Result
Now we have:
This simplifies to:
So the final answer is:
