Answer 1

Respuesta:

${x}^{3} - 5 = 22 \\ {x}^{3} = 22 + 5 \\ \\ {x}^{3} = 27 \\ x = \sqrt[3]{27} \\ x = 3$

${x}^{3} = 16 \\ x = \sqrt[3]{16} \\ x = 2.51$

${x}^{4} - 1 = 80 \\ {x}^{4} = 80 + 1 \\ x = \sqrt[4]{81} \\ x = 3$

$\sqrt{x} - 3 = 11 \\ \sqrt{x} = 11 + 3 \\ \sqrt{x} = 14 \\ x = {14}^{2} \\ x = 196$
