Expanding Logarithmic Expressions In Exercise, use the properties of logarithms to rewrite the expression as a sum, difference,

aev [14]

Answer:

The simplified expression is:

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

Step-by-step explanation:

We have those following logarithmic properties:

$\ln{\frac{a}{b}} = \ln{a} - \ln{b}$

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

$\ln{a^{n}} = n\ln{a}$

In this problem, we have that:

$\ln{x^{2}(x-1)}^{1/2}$

Applying these properties

$\frac{1}{2}*(\ln{x^{2} + \ln{(x-1)})$

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

Answer:

The dimensions are $16$ ft by $32$ ft

The quadratic equation is $W^{2}-256=0$

Step-by-step explanation:

we know that

the area of rectangle is equal to

$A=W*L$

where

L is the length side of rectangle

W is the width side of rectangle

in this problem

we have

$A=512\ ft^{2}$

so

$512=L*W$ -----> equation A

$L=2W$ ------> equation B

substitute equation B in equation A

$512=(2W)*W \\ 512=2W^{2} \\2W^{2}-512=0\\W^{2}-256=0$

$W=\sqrt{256}=16\ ft$

Find the value of L

$L=2W-----> L=2*16=32\ ft$
