Question

-5-{[(-3)³÷√9]-12÷(-2)²}+√4³

Answer 1

$-5 - \{ [ (-3)^{3} : \sqrt{9} ] - 12 : (-2)^{2} \} + \sqrt{ 4^{3} } = \\ - 5 - \{ [ -27 : 3 ] - 12 : (-2)^{2} \} + \sqrt{ 4^{3} } = \\ -5 - \{ (-9) - 12 : 4 \} + \sqrt{ 4^{3} } = \\ -5 - \{ (-9) - 3 \} + \sqrt{ 4^{3} } = \\ -5 - (-12) + \sqrt{ 4^{3} } = \\ -5 - (-12) + \sqrt{64} = \\ -5 - (-12) + 8 = \\ -5 + 12 + 8 = \\ 7 + 8 = \\ \fbox{15}$
