Question

Корінь енного степеня​

Answer 1

$1) \sqrt[4]{x + 2} = 1 \\ x + 2 = 1 \\ x = 1 - 2 \\ x = - 1$

$2) \sqrt[6]{x - 3} = - 2 \\ x∈∅ \\ 4) \sqrt[8]{2x - 4} = 2 \\ 2x - 4 = 256 \\ 2x = 256 + 4 \\ 2x = 260 \\ x = 130 \\ 5) \sqrt[7]{x {}^{2} - 3 } = 1 \\ x {}^{2} - 3 = 1 \\ x {}^{2} = 1 + 3 \\ x {}^{2} = 4 \\ x = \sqrt{4} \\ x = ±2 \\ x1 = - 2 \\ x2 = 2$
