EKSPONEN TOLONG DI BANTU YA DENGAN CARA MAKASIH BANYAK KAK

Bab Fungsi Eksponen

$3^{2x} - 10 \times 3^{x + 1} + 81 = 0\\ 3^{2x} - 10 \times 3^x \times 3^1 + 81 = 0\\ 3^{2x} - 30 \times 3^x + 81 = 0$

Misal a = 3^x

$a^2 - 30a + 81 = 0\\ (a - 27)(a - 3) = 0\\ a \left \{ {{27} \atop {3}} \right.$

3^x = 27

3^x = 3^3

x = 3

3^x = 3

3^x = 3^1

x = 1

Karena x₁ > x₂, maka

x₁ = 3 dan x₂ = 1

NIlai dari 3x₁ - x₂

= 3(3) - 1

= 27 - 1

= 26
