Mohon jawabannya,salah satu gakpapa

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Diket :
f(x) = 3ˣ

Tanya :
A] 
= f(x + 3) - f(x + 2) / f(x + 2)
=  3⁽ˣ ⁺ ³⁾ - 3⁽ˣ ⁺ ²⁾ / 3⁽ˣ ⁺ ²⁾
= (3ˣ.3³ - 3ˣ.3²) / 3ˣ.3²
= (27.3ˣ - 9.3ˣ) / 9.3ˣ
= 18.3ˣ / 9.3ˣ
= 18/9
= 2

B]
= f(x + 3). f(x - 2) / f(2x - 1)
= 3⁽ˣ ⁺ ³⁾. 3⁽ˣ ⁻ ²⁾ / 3⁽²ˣ ⁻ ¹⁾
= 3ˣ.3³. 3ˣ. 3⁻² / 3²ˣ . 3⁻¹
= 3ˣ.3ˣ. 3³⁻² / 3²ˣ. 3⁻¹
= 3ˣ⁺ˣ. 3¹ / 3²ˣ. 3⁻¹
= 3²ˣ. 3 / 3²ˣ. 3⁻¹
= 3/3⁻¹
= 3. 3
= 9
