Answer:
Explanation:
The expression can be simplified only if you take the same quantity out of both the top and bottom.
You can simplify the numbers by taking a factor of 3 out of the expression.
The numerator changes to 1 (because 3 / 3 = 1) and the denominator changes to 7 (because 21 / 3 = 7).
The variables can be eliminated through subtraction. The numerator variable is completely removed because you can subtract w³ from w⁵. This makes the denominator w² (because w⁵ - w³ = w²).
