Question 1084843

{{{(-3)^4 = 81}}}-> true, because we have negative sign inside parentheses; so,
{{{(-3)^4 =highlight((-3)(-3))highlight((-3)(-3))=highlight(9)*highlight(9) =81}}}

{{{-3^4 = -81}}}-> true,  because we have negative sign in front of parentheses like this {{{-(3^4)}}} ; so, {{{-3^4 =-(3*3*3*3)=-81}}}
