Answer:

Option B is correct

[tex]x-3 = \pm \sqrt{7}[/tex]

Step-by-step explanation:

Given the equation:

[tex](x-3)^2 = 7[/tex]

taking square root both sides we have;

[tex]\sqrt{(x-3)^2} = \pm \sqrt{7}[/tex]

Using exponent rules:

[tex]\sqrt[n]{x^n}=x[/tex]

then;

[tex]x-3 = \pm \sqrt{7}[/tex]

Therefore, the following statements follows from [tex](x-3)^2 = 7[/tex] is, [tex]x-3 = \pm \sqrt{7}[/tex]
