Does the problem look like this: {{{(3^2)(-4^2)}}} or this: {{{(3^2)(-4)^2}}} ?




If it looks like this: {{{(3^2)(-4^2)}}} then



{{{(3^2)(-4^2)}}} Start with the given expression



{{{(9)(-16)}}} Square each term



{{{-144}}} Multiply



OR


If it looks like this: {{{(3^2)(-4)^2}}} then



{{{(3^2)(-4)^2}}} Start with the given expression
