Kazeer [188]

Answer:

f( \frac{3}{ {x}^{2} - 16 } ) =  ({\frac{3}{ {x}^{2} - 16 }})^{2}  - 7(\frac{3}{ {x}^{2} - 16 }) + 12 \\  =  \frac{9}{ {x}^{4} - 32 {x}^{2}  + 256 }  -  \frac{21}{ {x}^{2}  - 16}  + 12

Expanding logarithmic Expression In Exercise,Use the properties of logarithms to rewrite the expression as a sum,difference,or m
ch4aika [34]

Answer:

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

Step-by-step explanation:

Consider the given expression is

\ln (x\sqrt[3]{x^2+1})

We need to rewrite the expression as a sum,difference,or multiple of logarithms.

\ln (x(x^2+1)^{\frac{1}{3}})        [\because \sqrt[n]{x}=x^{\frac{1}{n}}]

Using the properties of logarithm we get

\ln x+\ln (x^2+1)^{\frac{1}{3}}         [\because \ln (ab)=\ln a+\ln b]

\ln x+\frac{1}{3}\ln (x^2+1)        [\because \ln (a^b)=b\ln a]

Therefore, the simplified form of the given expression is \ln x+\frac{1}{3}\ln (x^2+1).
