Work Step by Step
Note, when using the calculator, it is necessary to use parenthesis, for the calculator will not necessarily know the correct order of operations. For instance, if division and addition are both performed, parenthesis may be necessary to indicate to the calculator that division is performed first according to PEDMAS. Thus, the given values of the variables are substituted, and the correct use of parenthesis on the calculator is shown below:
$$(-3)^6 = 729$$
