If x ^ 2 = 100, then x = 10.

For this case what you should know is the correct clearance of the following equation:

We then have two possible solutions:

x=+/- √(100)

Rewriting we have:

x=+/-10

Therefore, the solutions are:

x1=10 x2=-10

Answer:
A statement that is NOT true is:
If x^2 = 100, then x = 10.
