Question

calcula las siguientes raices​

Answer 1

Respuesta:

$a) \sqrt{(24 - 8 \times 5) \times (1 - 2)} = \sqrt{(24 - 40) \times ( - 1)} = \sqrt{ - 16 \times ( - 1)} = \sqrt{16} = ± 4$

$b) \sqrt[3]{ - 5 \times 15 + 47 \times ( - 3)} = \sqrt[3]{ - 75 + ( - 141)} = \sqrt[3]{ - 216} = - 6$

$c) \sqrt{12 \times 8 + 25 \times 4} = \sqrt{96 + 100} = \sqrt{196} = ±14$

$d) \sqrt[3]{ - 17 \times 8 - 21 \times 7 - 19 \times 8 - 11 \times 7} = \sqrt[3]{ - 136 - 147 - 152 - 77} = \sqrt[3]{512} = - 8$

$e) \sqrt[4]{ - 57 \div 3 + 2 \times (8 \times 5 + 5 \times 2)} = \sqrt[4]{ - 57 \div 3 + 2 \times (40 + 10)} = \sqrt[4]{ - 57 \div 3 + 2 \times 50} = \sqrt[4]{ - 19 + 100} = \sqrt[4]{81} = ±3$
