32
Answer explanation
Untuk menyederhanakan ekspresi (2^3) * (2^2), kita gunakan aturan perkalian eksponen: a^m * a^n = a^(m+n). Jadi, (2^3) * (2^2) = 2^(3+2) = 2^5 = 32. Jawaban yang benar adalah 32.

am x an = am-n
am x an = am/n
am x an = am+n
am x an = amn
Answer explanation
Sifat dari a^m * a^n adalah a^(m+n). Ini berarti ketika kita mengalikan dua bilangan berpangkat dengan basis yang sama, kita cukup menjumlahkan eksponen mereka.
