Answer:
x = 2
Step-by-step explanation:
Using the rules of logarithms
• log [tex]x^{n}[/tex] ⇔ n logx
• log x = log y ⇒ x = y
Given
2 ln 4x = 2 ln 8
ln (4x)² = ln 8²
ln 16x² = ln 64, hence
16x² = 64 ( divide both sides by 16 )
x² = 4 ( take the square root of both sides )
x = [tex]\sqrt{4}[/tex] = 2
