Question

pls help me by solving this​

Answer 1

Step-by-step explanation:

(3)^2x+5= (3)^2x+3+72

(3)^2x+5=(3)^2x+3 +( 3×3×2×2×2)

(3)^2x+5=(3)^2x+3 + 3².2³

(3)^2x.(3)^5=(3)^2x(3)^3+3².2³

(3)²[(3)^2x(3)³]=(3)²[3^2x.3+2³]

3^2x.3³=3^2x.3+2³

3^2x(3³-3)=2³

3^2x(24)=8

3^2x=8/24

3^2x=1/3

3^2x=3^-1

2x=-1

x=-1/2

hope u understand

mark as brilliant
