Expanding logarithmic Expression In Exercise,Use the properties of logarithms to rewrite the expression as a sum,difference,or m

Liono4ka [1.6K]

Answer:

$\ln{(3x)}+\ln{(x+1)}-2\ln{(2x+1)}$

Step-by-step explanation:

we need to keep in mind two properties of log:

$\ln{ab}=\ln{a}+\ln{b}$

$\ln{\dfrac{a}{b}}=\ln{a}-\ln{b}$
$\ln{a^b}=b\ln{a}$

$\ln{\dfrac{3x(x+1)}{(2x+1)^2}}$

$\ln{\left(\dfrac{3x(x+1)}{(2x+1)^2}\right)}\\\ln{(3x(x+1))}-\ln{((2x+1)^2)}\\\ln{(3x)}+\ln{(x+1)}-\ln{((2x+1)^2)}$

$\ln{(3x)}+\ln{(x+1)}-2\ln{(2x+1)}$

this is the rewritten expression!

Zack wants to make a profit of more than $300 for painting 4 identical rooms. The profit he makes is equal to the amount he is p

Lelu [443]

Answer:

n-4(32.5) > 300;n > 430

Step-by-step explanation:

Simplify: 300 = 4n - 130

Add 130 to each side. 430 = 4n

Divide by 4 on each side: 107.50= n

300 = 4(107.50) - 130? True

This tells us he must be paid $107.50 to make $300 exactly. Anything larger than $107.51 and up will make more than $300.
