Answer 2

To find the value of x in the expression √(x^2 + 9), we can set up an equation and solve for x.

√(x^2 + 9) = 0

To isolate the square root, we square both sides of the equation:

(x^2 + 9) = 0

Now, we subtract 9 from both sides of the equation:

x^2 = -9

Since the square of a real number cannot be negative, this equation has no real solutions. Therefore, there is no real value of x that satisfies the equation √(x^2 + 9) = 0.
