Answer:

x=8.33

Step-by-step explanation:

given [tex]ln4+ln(3x)[/tex]=2

ac/logrithmic formula,

[tex]ln(a)+ln(b)[/tex]=[tex]ln(a)\times ln(b)[/tex]

[tex]ln(4)+ln(3x)[/tex]=[tex]ln(12x)[/tex]

ac/question,

ln(12x)=2

12x=10^2=100

x=[tex]\frac{100}{12}[/tex]=8.33

x=8.33  answer

Answer:

[tex]x = 0.62 (Approximated)[/tex]

Step-by-step explanation:

Given: ln(4) + ln(3x) = 2

Required: Solve for x

To solve this;  follow the highlighted steps

Step 1: Write out the expression

[tex]ln(4) + ln(3x) = 2[/tex]

Step 2: Apply law of logarithm which states that [tex]ln(a) + ln(b) = ln(a * b).[/tex]

So, Similarly: [tex]ln(4) + ln(3x) = 2[/tex] becomes

[tex]ln(4 * 3x) = 2[/tex]

Step 3: Solve the bracket

[tex]ln(12x) = 2[/tex]

Step 4:  Take exponent of both sides

[tex]12x = e^{2}[/tex]

Step 5:  Divide both sides by 12

[tex]\frac{12x}{12} = \frac{e^{2}}{12}[/tex]

Which gives

[tex]x = \frac{e^{2}}{12}[/tex]

Step 6: Solve right hand side of the equation

[tex]x = \frac{7.38905609893}{12}[/tex]

[tex]x = 0.61575467491[/tex]

[tex]x = 0.62 (Approximated)[/tex]
