Jawaban dan Penjelasan
Berikut ini adalah pilihan jawaban terbaik dari pertanyaan diatas.
17² - 15²
= 289 - 225
=> 64(Opsi C)
Eksponen adalah Suatu hasil dari perkalian yg diulang ulang
Dimana,
a = basis
b = pangkat
Eksponen Menyederhanakan:
12² × 12²
= 12^(²+²)
= 12^4
= 12 × 12 × 12 × 12
= 144 × 144
=> 20.736
