Best Answer

${\mathtt{\,-\,}}{{\mathtt{4}}}^{{\mathtt{2}}}{\mathtt{\,\small\textbf+\,}}{\mathtt{5}} = -{\mathtt{11}}$

${\left(-{\mathtt{4}}\right)}^{{\mathtt{2}}}{\mathtt{\,\small\textbf+\,}}{\mathtt{5}} = {\mathtt{21}}$

${\mathtt{\,-\,}}{{\mathtt{4}}}^{{\mathtt{2}}}{\mathtt{\,\small\textbf+\,}}{\mathtt{5}} = -{\mathtt{11}}$

${\left(-{\mathtt{4}}\right)}^{{\mathtt{2}}}{\mathtt{\,\small\textbf+\,}}{\mathtt{5}} = {\mathtt{21}}$

Exactly. (-4)²=16 but -4²=-16, so -4²+5=-16+5=-11.
