x2 = 16, therefore x = 4. Is this a valid conclusion? If no, give a counterexample

False. What other value squared = 16 other than 4? It will be your counterexample.

She promised to do this but left. The counterexample is -4. x2 = 16 x^2 - 16=0 (x + 4)(x -4) = 0 x = -4 or x = -6. Every number has two square roots.
