Since you can't take the square root of a negative number, the expression under the square root must be equal to, or greater than, zero. Just solve this inequality, with the expression under the square root.
If I understand correctly, the expression under the root is 9x2-4. For the inequality, get the critical points through an equation first: 9x2-4 = 0; 9x2 = 4; x2 = 4/9; x = plus-or-minus 2/3. Analyzing any points to the left of -2/3, between -2/3 and 2/3, and to the right of 2/3, you quickly see that the inequality is fulfilled for any number that is either <= -2/3, or >= 2/3.

What is the square root of x if it equals to 3?
square root of x = 3 Since the square root of a number is basically that number to the power of 1/2, if you square both sides it will cancel out the square root.(x1/2)2 = 32x = 32x = 9Since 3 squared is 9, x equals 9.
