Formula Explained

The basic formula for exponentiation is:

result = baseexponent

For negative bases, the result depends on whether the exponent is an integer or a fraction:

  • If the exponent is an integer, the result will be negative if the base is negative and the exponent is odd.
  • If the exponent is a fraction, the result will be complex and may require imaginary numbers.

Note: This calculator handles real numbers only. For complex number calculations, you may need specialized software.

Worked Examples

Example 1: Positive Base with Positive Exponent

Calculate 23:

23 = 2 × 2 × 2 = 8

Example 2: Negative Base with Integer Exponent

Calculate (-3)2:

(-3)2 = (-3) × (-3) = 9

Example 3: Negative Base with Fractional Exponent

Calculate (-4)0.5:

(-4)0.5 = √(-4) = 2i (where i is the imaginary unit)

Frequently Asked Questions

Can this calculator handle complex numbers?

No, this calculator is designed for real numbers only. For complex number calculations, you may need specialized mathematical software.
