Definition of nth root
WebTherefore the nth roots of complex number z = r (cosθ + i sinθ ) are. If we set ω = the formula for the n th roots of a complex number has a nice geometric interpretation, as shown in Figure. Note that because ω = n√r the n roots all have the same modulus n√r they all lie on a circle of radius n√r with centre at the origin. WebBy definition, the nth root of a number can be calculated by raising that number to the power of 1/n. Exponents are entered using the exponentiation operator (^), with a number on the left and power on the right. So, in this …
