SUMMARY
The Cartesian form of the expression 1/(2^j) is derived using Euler's formula and properties of exponents. The conversion process involves rewriting 1/(2^j) as 2^-j, which can be expressed in exponential form as 2^(e^(-πj/2)). The real part, a, is calculated as cos(-π/2) resulting in 0, while the imaginary part, b, is sin(-π/2) yielding -1. Thus, the Cartesian form is 0 - 1j.
