If x^2 = 231, which of the following is closest to a potential value of x?  Choose the most appropriate option: A) -127 B) -11 C) 12 D) 13 E) 15
Here the thing we must not forget is that X^even has two potential solutions   =&gt; x =+- √231 =&gt; +- 15 (approx)   this value is closer to 15   Hence 15 is correct.
