How the math works A whole-number exponent means multiplying the base by itself that many times. A negative exponent means 1 divided by the positive power. An exponent of 0.5 is the square root. The formula: base^exponent = base × base × … (exponent times). A negative exponent means 1 ÷ the positive power. An exponent of 1/n is the n-th root, e.g. 0.5 is the square root.
