Hey there! I will give the following steps, if you have any questions feel free to ask me in the comments below. Good luck!

Step 1: Simplify 21.39 + 9 to 30.39.

Basically, add 21 + 9 which equals 30, then add .39 to the end. You will then get 30.39.

30.39 = x

Step 2: Switch sides.

x = 30.39

Expand each expression

Answer:

Option B - $\ln(\frac{4y^5}{x^2})=\ln 4+5\ln y-2\ln x$

Step-by-step explanation:

Given : Expression $\ln(\frac{4y^5}{x^2})$

To find : Expand each expression ?

Solution :

Using logarithmic properties,

$\ln (\frac{A}{B})=\frac{\ln A}{\ln B}=\ln A-\ln B$

and $\ln (AB)=\ln A+\ln B$

Here, A=4y^5 and B=x^2

$\ln(\frac{4y^5}{x^2})=\frac{\ln 4y^5}{\ln x^2}$

$\ln(\frac{4y^5}{x^2})=\ln 4y^5-\ln x^2$

$\ln(\frac{4y^5}{x^2})=\ln 4+\ln y^5-\ln x^2$

Using logarithmic property, $\logx^a=a\log x$

$\ln(\frac{4y^5}{x^2})=\ln 4+5\ln y-2\ln x$

Therefore, option B is correct.

Find the inverse of the function. y = x2 + 4x + 4

QveST [7]

Factors of 4: 2 and 2
y= (x+2)²
+√y or -√y = x+2

x= 2+√y , 2-√y

interchange variables
y= 2+√x , 2-√x

f ⁻¹(x) = 2 + √x, 2 - √x
