Jika :9ⁿ = 4
maka :
3²ⁿ = 4
3ⁿ = √4
3ⁿ = +/- 2
Jadi ada dua kemungkinan yaitu :
3ⁿ = - 2 atau 3ⁿ = 2
Sehingga :
= 4.3ⁿ⁺¹ - 27ⁿ
= 4.3ⁿ.3 - (3³)ⁿ
= 12.3ⁿ - (3ⁿ)³
# Kemungkinan Pertama : Jika 3ⁿ = - 2, maka :
= 12.3ⁿ - (3ⁿ)³
= 12.(- 2) - (- 2)³
= - 24 - (- 8)
= - 24 + 8
= - 16
# Kemungkinan Kedua : Jika 3ⁿ = 2, maka :
= 12.3ⁿ - (3ⁿ)³
= 12.(2) - (2)³
= 24 - (8)
= 16
