how do you express a root in keyboard math, like the cube root of a number?

Question

and if "man" pops up report it as a spambot.

Answer 1

Use a fractional exponent. Square root means ^(1/2), cube root means ^(1/3) etc. To understand why this is, consider the laws of exponents. Since (a^b)^c = a^(bc), sqrt (a^2) = |a| = |a^1|, it follows that we define fractional exponents a^(1/n) = nth root of a.

Answer 2

567^(1/3)
