Root of a square-x÷a square+x |
|
Answer» Step-by-step explanation: The term 'the square root of X' is not QUITE precise as there are USUALLY 2 √ X and − √ X
√ x 2 = | x |
This is the positive square root of x 2 . − √ x 2 = − | x | is also a square root of x 2
It's tempting to say √ x 2 = x , but that's only true for x ≥ 0 |
