According to Wikipedia,

"In mathematics, a multiplicative inverse or reciprocal for a number x, denoted by 1/x or x^−1, is a number which when multiplied by x yields the multiplicative identity, 1."

Accordingly, the multiplicative inverse of 1 + i is

1/(1+i) = (1-i)/[1-i)(1+i)]

= (1-i)/2

If you want the multiplicative inverse of z^2, where z = 1+i,

that would be 1/z^2 = 1/(1+i)^2
