_____________
Eksponen atau Perpangkatan adalah Operasi Khusus Matematika untuk Mengalikan Suatu Bilangan dengan Bilangan itu sejumlah dengan eksponen-nya (^)
Perpangkatan Di-Notasikan Sebagai:
= Aⁿ
= A × A × A × A...... (n faktor)
Contoh:
2² = 2 × 2 = 4
2³ = 2 × 2 × 2 = 4 × 2 = 8
2⁴ = 2 × 2 × 2 × 2 = 4 × 4 = 16
dst....
__________
= 2³
= 2 × 2 × 2
= (2 + 2) × 2
= 4 × 2
= 4 + 4
= 8 (B.)
Jadi, Hasil dari 2³ adalah 8
