Question

a. [60 ÷ (18 - 3) + 17] × [$3^{2}$ + 2 × ($6^{2}$ - $5^{2}$)]

b. 120 - {24 ÷ 4 + [$5^{2}$ + ( + 2 × $3^{2}$) - 7 × 4 ÷ 14}

Answer 1

Respuesta:

a. [60 ÷ (18 - 3) + 17] × [ 3²+ 2 × ( 6²-5²)]

[60 / 15+17] * [9+2*(36-25)]

4+17 * [9+2*11]

21*[9+22]

21*31

651

Explicación paso a paso:

b. 120 - {24 ÷ 4 + [5² + ( + 2 ×3² ) - 7 × 4 ÷ 14}

120- {24/4+[25+(2*9)-28/14]}

120-{6+[25+18-28/14]}

120-{6+[25+18-2]}

120-{6+41}

120- 47
