Resposta:
A) X²= 64
[tex] {x}^{2} = 64 \\ x = \sqrt{64} \\ x = 8[/tex]
B) X²= 25
[tex] {x}^{2} = 25 \\ x = \sqrt{25} \\ x = 5[/tex]
C) X²=144
[tex] {x}^{2} = 144 \\ x = \sqrt{144} \\ x = 12[/tex]
D) X²= 81
[tex] {x}^{2} = 81 \\ x = \sqrt{81} \\ x = 9[/tex]
E) X²= 36
[tex] {x}^{2} = 36 \\ x = \sqrt{36} \\ x = 6[/tex]
