Math Problem Statement

log(x^2/^3 √(x+8)^5)

Solution

The expression you have is:

log(x2(x+8)53)\log\left(\frac{x^2}{\sqrt[3]{(x+8)^5}}\right)

Let's break it down:

Step 1: Simplify the logarithmic expression

Using logarithmic rules, we can simplify the expression:

  1. Logarithm of a quotient: log(ab)=log(a)log(b)\log\left(\frac{a}{b}\right) = \log(a) - \log(b)

    Applying this rule to the given expression: [ \log\left(\frac{x^2}{\sqrt[3]{(x+8)^5}}\right) = \log(x^2) - \log\left(\sqrt[3]{(x+8)^5}\right) ]

Step 2: Simplify each term

  1. Logarithm of a power: log(ab)=blog(a)\log(a^b) = b \log(a)

    So for the first term: log(x2)=2log(x)\log(x^2) = 2 \log(x)

    Now, simplifying the second term: log((x+8)53)=log((x+8)5/3)=53log(x+8)\log\left(\sqrt[3]{(x+8)^5}\right) = \log\left((x+8)^{5/3}\right) = \frac{5}{3} \log(x+8)

Step 3: Combine the results

The expression now becomes: 2log(x)53log(x+8)2 \log(x) - \frac{5}{3} \log(x+8)

Thus, the simplified form of the original expression is: 2log(x)53log(x+8)2 \log(x) - \frac{5}{3} \log(x+8)
