Answer:
x = 11
Step-by-step explanation:
You are solving for x. Note the equal sign, what you do to one side, you do to the other. Isolate the variable, x, by rooting both sides:
√(x²) = √(121)
x = √121
x = √(11 * 11)
Note that when you have two of the same number multiplied within the root, they are squared, which makes them into a whole number.
x = √11 * √11 = 11
x = 11 is your answer.

Answer:
x = 11
Step-by-step explanation:
If you have a scientific calculator, that can help you solve this problem.
To get rid of the square [tex](x^{2} )[/tex] on the X value you need to perform the opposite of a square to cancel it out.
The opposite of a square is a square root [tex](\sqrt{x^{2} })[/tex]
So:
[tex]\sqrt{x^{2} } = \sqrt{121}[/tex] (the root gets rid of the power of 2)
[tex]x = 11[/tex] (This is your answer)
