Question

WHAT IS THE ANS TO THIS PROBLEM???? $\sqrt{x} \\ x^{2}$

Answer 1

For example, if we let x = -7, then sqrt(x2) = sqrt((-7)2) = sqrt(49) = 7, which is not equal to x. In general, the square root of the square of a real number is always equal to the absolute value of that number. In other words, the equation sqrt(x2) = |x| is true for all real numbers x.
