The answer is C. 45. Here's the work to prove it: c = correct answer, i = incorrect answer;

-2(c + i = 50)

2c - 3i = 75

-2c - 2i = -100

-5i/-5 = -25/-5

i = 5

c + 5 - 5 = 50 - 5

c = 45

What is ln x + 2 ln y − ln z written as a single logarithm.

MA_775_DIABLO [31]

Answer:

$\ln \frac{xy^2}{z}$

Step-by-step explanation:

Given expression:

$\ln x+2\ln y-\ln z$

To write the given expression in single logarithm.

Solution:

We will apply the logarithm properties to write the expression in single logarithm.

We have:

$\ln x+2\ln y-\ln z$

Using power rule : [ $a\ln b= \ln b^a$ ]

⇒ $\ln x+\ln y^2-\ln z$

Using product rule: [ $\ln a+\ln b=\ln ab$ ]

⇒ $\ln xy^2-\ln z$

Using quotient rule. [ $\ln a - \ln b = \ln\frac{a}{b}$ ]

⇒ $\ln \frac{xy^2}{z}$

Thus, we successfully converted the expression to a single logarithm expression.
