Fourth Power Root Calculator

1. The fourth power root is a mathematical concept, which refers to the fourth power root of one number a is another number b, so that b⁴=a.

2. The fourth-power root is the number that multiplies a number by itself three times to get the original number. Fourth-power roots are commonly used in fields such as mathematics, physics, and engineering.

3. Properties of the fourth-power root:

(1) Uniqueness: For any positive number a, its fourth-power root is the only positive number. For example, the fourth root of 16 is 2 because 2⁴=16;

(2) Negative numbers: Negative numbers also have a fourth-power root, but they are plural. For example, the fourth-power root of -16 is 2i and -2i because (2i)⁴ = -16;

(3) The fourth root of zero: 0 is 0, because 0⁴=0;

(4) Symbol: The fourth root of a positive number is a positive number, and the fourth root of a negative number is a complex number.
