Powers and Roots of Phasors Powers and roots of complex numbers can be found very conveniently in polar form. If the complex number is not in polar form, it is always advisable to convert the number to this form and then carry out these algebraic operations. (1) Powers. Suppose it is required to find the cube of the phasor 2 ∠ 10°. For this purpose, the phasor has to be multiplied by itself three times. (2) Roots. Let us proceed backward with the above given example. Suppose we are to find the cube root of 8 ∠ 30^{0. }It is clear that
