(a-b) n-th power formula extension

The (a-b)ⁿ formula extension is a small web computing tool, based on which n values are given, where n is the factor (a-b).

For example, if the value of n is 2, the expression \((a-b)^2 = a^2-2ab-b^2\).

This formula extension can be used to find expressions (a-b)²，(a-b)³，(a-b)⁴ up to (a-b)ⁿ. Provide n values in the given text box and press the Calculate button to provide the appropriate expression.
