Expand: In 2a^3/b^4

dem82 [27]

Answer:

$(A)ln 2+3lna-4ln b$

Step-by-step explanation:

Given the expression: $ln \dfrac{2a^3}{b^4}$

We apply the following laws of logarithm to expand:

$Log (ab)=Log a+Log b\\Log(a/b)=Log a-Log b\\Log a^x=xLog a$

Therefore:

$ln \dfrac{2a^3}{b^4}=ln 2a^3-ln b^4\\=ln 2+lna^3-ln b^4\\=ln 2+3lna-4ln b$

Slope Formula: $m=\frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

Step 1: Define

Find points from table

Point (0, 3)

Point (1, 7)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m. Rate of change and slope are the same.

Substitute [SF]: $m=\frac{7-3}{1-0}$
Subtract: $m=\frac{4}{1}$
Divide: $m=4$

Evaluate 6x for each value of x. x = 2/3

Leviafan [203]

You have only listed one value for 'x'.

If 'x' is 2/3, then 6x is (6 times 2/3). That's 12/3 or 4 .
