B)x3 = -8 => x =
C)2x = 32 => x =
D) √x = 5 => x =
E) √x = 1 => x =

Answer 1

Explicação passo-a-passo:

$A)\\ x^2=16\\ x=\pm\sqrt{16} \\ x=\pm4\\ \\ B)\\ x^3=-8\\ x=\sqrt[3]{-8} \\ x=\sqrt[3]{-2^3} \\ x=-2\\ \\ C)\\ 2^x=32\\ 2^x=2^5\\ x=5\\ \\ D)\\ \sqrt{x} =5\\ x=5^2\\ x=25\\ \\ E)\\ \sqrt{x} =1\\ x=1^2\\ x=1$
