[tex] R_{gh} = \frac{R}{2} + 2 [/tex]
[tex] R_{gh} [/tex] = ²/₂ + 2
[tex] R_{gh} [/tex] = 3 Ω

[tex] R_{bc} [/tex] = R / 2
[tex] R_{bc} [/tex] = 4 / 2
[tex] R_{bc} [/tex] = 2 Ω

[tex] R_{ad} [/tex] = 3 • 2
[tex] R_{ad} [/tex] = 6 Ω

[tex] R_{ie} [/tex] = (2 • 2) + ( ⅓ + ⅙ )⁻¹
[tex] R_{ie} [/tex] = 4 + (³/₆)⁻¹
[tex] R_{ie} [/tex] = 4 + (⁶/₃)
[tex] R_{ie} [/tex] = 4 + 2
[tex] R_{ie} [/tex] = 6 Ω
