The multiplicative inverse of a complex number is found by taking the complex conjugate of the number and dividing by the square of its magnitude. For the complex number 3-i, the complex conjugate is 3+i. The magnitude of 3-i is sqrt(3^2 + (-1)^2) = sqrt(9 + 1) = sqrt(10). Therefore, the multiplicative inverse of 3-i is (3+i) / 10.

Multiplicative Inverse of a NumberReciprocal The reciprocal of x is . In other words, a reciprocal is a fraction flipped upside down. Multiplicative inverse means the same thing as reciprocal. For example, the multiplicative inverse (reciprocal) of 12 is and the multiplicative inverse (reciprocal) of is . Note: The product of a number and its multiplicative inverse is 1. Observe that ·= 1.
