Question

That is the whole parentheses is -3rd power not X to the -3rd power also express everything in the end as a positive ones

Answer the bold

Answer

Let’s solve the first problem. The problem is to simplify and express the answer with positive exponents.
The expression is:
Step 1: Apply the power rule to each parenthesis.
For the first term:
For the second term:
Step 2: Apply the power rule .
For the first term:
For the second term:
Step 3: Multiply the simplified terms.
Step 4: Group the coefficients and variables with the same base.
Step 5: Apply the product rule .
For the coefficients:
For the y terms:
For the x terms:
Step 6: Simplify the numerical coefficient.

Divide both numerator and denominator by their greatest common divisor.


So,
Step 7: Simplify .
(for )
Step 8: Combine all simplified parts.
Step 9: Express the answer with positive exponents.
Use the rule .
The final answer is .
