Question

me podrían ayudar a sacar equis en estás operaciones

x³=8



5x²=125



6x²-8=52


y³-12=15



8b²=128

por favor​

Answer 1

Respuesta:

${x}^{3} = 8 \\ x = \sqrt[3]{8} \\ x = 2 \\ \\ 5 {x}^{2} = 125 \\ {x}^{2} = \frac{125}{5} \\ {x}^{2} = 25 \\ x = \sqrt{25} \\ x = 5 \\ \\ 6 {x}^{2} - 8 = 52 \\ 6 {x }^{2} = 60 \\ {x}^{2} = \frac{60}{6} \\ {x }^{2} = 10 \\ x = \sqrt{10}$

${y}^{3} - 12 = 15 \\ {y}^{3} = 27 \\ y = \sqrt[3]{27} \\ y = 3 \\ \\ 8 {b}^{2} = 128 \\ {b}^{2} = \frac{128}{8} \\ {b}^{2} = 16 \\ b = \sqrt{16} \\ b = 4$
