Square both sides of the equation and you will get:

x < 49      Does that help ya with the answer(s)?

sqrt (x) < 7      square both sides

 

x < 49

 

But  x also has to be  ≥ 0

 

So.....the solutions are on this interval

 

0  ≤  x  < 49

The answer cannot be negative because then it will be a complex, or imaginary number!
