Question

calcule o valor de x, me ajudem!por favor

Answer 1

a)
${x}^{3} = 8 \\x = \sqrt[3]{8} \\ x = 2 \\ \\ b) {x}^{2} = \frac{1}{16} \\ \\ x = \sqrt{ \frac{1}{16} } \\ x = \frac{ \sqrt{1} }{ \sqrt{16} } \\ x = \frac{1}{4} \\ \\ c) {2}^{5} = x \\ \: x = 32 \\ \\ d) {9}^{x} = 27 \\ {3}^{2x} = {3}^{3} \\ 2x = 3 \\ x = \frac{3}{2 } \\ x = 1.5 \\ \\ e) ({{ \frac{1}{2} }})^{x} = 32 \\ {2}^{ - x} = {2}^{5} \\ x = - 5$

[tex]{x}^{3} = 8 \\x = \sqrt[3]{8} \\ x = 2 \\ b) {x}^{2} = \frac{1}{16} \\ \\ x = \sqrt{ \frac{1}{16} } \\ x = \frac{ \sqrt{1} }{ \sqrt{16} } \\ x = \frac{1}{4}//
