Frequently asked questions
What happens if I enter a negative base with a fractional exponent?
If the base is negative and the exponent is not an integer, the result may be a complex number, which is not supported. The calculator will show an error indicating the result is undefined.
Can I use decimal exponents?
Yes, decimal exponents are treated as real numbers. For example, 4^0.5 equals 2, which is the square root of 4.
Why does the result show in scientific notation?
Scientific notation is used when the result is very large or very small, making it easier to read. For example, 10^20 is displayed as 1.00000000e+20.
