Frequently Asked Questions

How do fractional exponents work?

A fractional exponent like x^(1/2) equals the square root of x. More generally, x^(m/n) equals the nth root of x raised to the m power. Enter 0.5 as the exponent to calculate square roots, 0.333 for cube roots, etc.

What about negative exponents?

A negative exponent x^(-n) equals 1/(x^n). For example, 2^(-3) = 1/8 = 0.125. The calculator handles negative exponents and displays the reciprocal form.
