Question

Answer

The user has provided an image containing a step-by-step mathematical simplification problem involving exponents. I will reconstruct and solve the problem based on the visible steps.
The original expression appears to be:
We know that .
Step 1: Separate the fraction into individual terms.
Substituting :
Step 2: Simplify each term using the rule .
  • Term 1:
    (This matches the line: )
  • Term 2:
    (This matches the line: )
  • Term 3:
    The next steps in the image calculate the exponent .
Step 3: Calculate the exponent for Term 3.
To subtract the fractions, find a common denominator, which is .
The image shows the calculation for converting the denominators:
(These match the lines: and )
Now combine them:
(This matches the line: )
So, the third term is .
Step 4: Combine the simplified terms.
The expression simplifies to:
(This matches the boxed result: )
Step 5: Rewrite the negative exponent term.
Using the rule :
The final simplified expression is:
(This matches the final boxed result.)
The final answer is:
