3. Diberikan \( H \) subgroup dari grup \( G \) maka himpunan semua koset kiri yaitu \( \{x H \mid x \in G\} \) membentuk partisi pada \( G \). Buktikan ! 4. Diberikan \( H \) subgroup dari grup \( G \) dan \( x \in G \), maka order dari \( H \) sama dengan order dari \( x H \) dan sama dengan order dari \( H x \) yaitu: \[ |H|=|x H|=|H x| \text {. } \] 5. Buktikan bahwa jika diberikan \( H \) subgrup dari \( G \), maka terdapat suatu korespondensi \( 1-1 \) antara himpunan semua koset kiri dari \( H \) di \( G \) dengan himpunan semua koset kanan dari \( H \) di \( G \). Lebih lanjut, banyaknya koset kiri dari \( H \) di \( G \) sama dengan banyaknya koset kanan dari \( H \) di \( G \).
