Answer:

x = - 8 atau 3

Explanation:

3ˣ² × 3⁵ˣ = 3²⁴

Penarikan:

Mᵃ × Mᵇ = Mᵃ⁺ᵇ

3ˣ² × 3⁵ˣ = 3ˣ²⁺⁵ˣ

Karena itu

3ˣ² × 3⁵ˣ = 3²⁴

3ˣ²⁺⁵ˣ = 3²⁴

x² + 5x = 24

Mengatur kembali

x² + 5x - 24 = 0

Pemecahan dengan faktorisasi

x² - 3x + 8x - 24 = 0

x (x - 3) + 8 (x - 3) = 0

(x + 8) (x - 3) = 0

x + 8 = 0 atau x - 3 = 0

x = - 8 atau x = 3

Karena itu,

x = - 8 atau 3
