Math Problem Statement

2log(9)-3log(x) simplify

Solution

To simplify 2log(9)3log(x)2\log(9) - 3\log(x), we can use the properties of logarithms.

Step-by-Step Solution

  1. Use the Power Rule: The power rule of logarithms states that alog(b)=log(ba)a \log(b) = \log(b^a). 2log(9)=log(92)=log(81)2\log(9) = \log(9^2) = \log(81) and 3log(x)=log(x3).3\log(x) = \log(x^3).

    Substituting these into the expression, we get: log(81)log(x3).\log(81) - \log(x^3).

  2. Use the Quotient Rule: The quotient rule of logarithms states that log(a)log(b)=log(ab)\log(a) - \log(b) = \log\left(\frac{a}{b}\right). log(81)log(x3)=log(81x3).\log(81) - \log(x^3) = \log\left(\frac{81}{x^3}\right).

Final Answer

The simplified form is: log(81x3).\log\left(\frac{81}{x^3}\right).
