Question

4 cálculos combinados
alguien me ayuda porfa​

Answer 1

A)

$(4 + 7 \times 4) \div 8 + 15 \times 7 - 11 \times 11 = \\ (4 + 28) \div 8 + 105 - 121 = \\ 32 \div 8 + 105 - 121 = \\ 4 + 105 - 121 = \\ 109 - 121 = - 12$

B)

${6}^{3} \div 24 + \sqrt{25} - {5}^{0} + 6 \times 2 = \\ 216 \div 24 + 5 - 1 + 12 = \\ 9 + 4 + 12 = \\ 13 + 12 = 22$

C)

$315 \div 9 - (8+ 5 \times 20) \div 12 - 5 \times 5 = \\ 35 - (8 + 100) \div 12 - 25 = \\ 35 - (108) \div 12 - 25 = \\ 35 - 108\div 12 - 25 = \\ 35 - 9 - 25 = \\ 26 - 25 = 1$
