Answer 1

Respuesta:

$3 + (6 + 2( {2}^{3} \div 4 + 3.2) - 7.2) + 9 \div 3 = 15.2$

Explicación paso a paso:

$3 + (6 + 2( {2}^{3} \div 4 + 3.2) - 7.2) + 9 \div 3 \\ 3 + (6 + 2( {2}^{3} \div {2}^{2} + 3.2) - 7.2) + 3 \\ 3 + (6 + 2(2 + 3.2) - 7.2) + 3 \\ 3 + (6 + 2 \times 5.2 - 7.2) + 3 \\ 3 + (6 + 10.4 - 7.2) + 3 \\ 3 + 9.2 + 3 \\ 12.2 + 3 \\ 15.2$
