What are conditions to find the Nth Root of a Number?
1) The number "x" must be positive if you want to find the nth root of it. This is because roots are only defined for positive numbers. For example, you can find the square root of 9 (which is 3), but you can't find the square root of -9.
2) The root degree "n" must be a positive integer. This means that you can find the square root, cube root, fourth root, etc. of a number, but you can't find the 1.5th root or the square root of a square root.
3) The value of "y" (the nth root) will always be positive if "x" is positive. For example, if you want to find the square root of 4, the answer will be 2, not -2.
