Question

Please help determine if this is true

Answer 1

Answer:

False.

Step-by-step explanation:

√x = -7 ... Square both sides

x = 49

This question is kind of tricky, and there's a few ways to look at it, but I think that's the most understandable. Another thing you can notice is that if x = -49, you can't take the square root of a negative value (unless you're including complex values with the imaginary "i"), or that the square root of a value is -7, the original value would have been (-7)*(-7) which gives you a POSITIVE 49, not a negative one.
