G. 33: 3 + 202 - (22+52) - V9 x 4

Answer 1

Respuesta:

$\boxed{\boxed{\mathbf{\bold{\red{\text{operaciones \: combinadas}}}}}}$

$a) \: 2 \times 20 + 8 \times 2 - (16 - 12) \times 3 - \sqrt{64 \div 4} \\ 2 \times 20 + 8 \times 2 - (4) \times 3 - \sqrt{64 \div 4} \\ 2 \times 20 + 8 \times 2 - (4) \times 3 - \sqrt{16} \\ 2 \times 20 + 8 \times 2 - (4) \times 3 - 4 \\ 40 + 16 - 12 - 4 \\ \Longrightarrow\mathbf\green{40}$

$b) \: 9 + \sqrt{36 + 64} - 10 \div {5}^{0} + {5}^{2} \times \sqrt{42 + 7} \\ 9 + \sqrt{100} - 10 \div 0 + 25 \times \sqrt{49} \\ 9 + 10 - 10 \div 0 + 25 \times 7 \\ 9 + 10 - 0 + 175 \\ \Longrightarrow\mathbf\orange{194}$

${3}^{3} \div 3 + {20}^{2} - ( {2}^{2} + {5}^{2}) - \sqrt{9 \times 4} \\ {3}^{3} \div 3 + {20}^{2} - (4 + 5) - \sqrt{9 \times 4} \\ {3}^{3} \div 3 + {20}^{2} - (9) - \sqrt{9 \times 4} \\ 27 \div 3 + 400 - (9) - \sqrt{36} \\ 27 \div 3 + 400 - (9) - 6 \\ 9 + 400 - (9) - 6 \\ \Longrightarrow\mathbf\blue{396}$

$a)\large\boxed{\Longrightarrow\mathbf\green{40 \: \: }} \\ b)\large\boxed{\Longrightarrow\mathbf\orange{196}} \\ c) \large\boxed {\Longrightarrow\mathbf\blue{394}}$
