Full solution

Q. log9(x316)\log_{9}\left(\frac{x^{3}}{16}\right)
  1. Apply Logarithm Property: We need to simplify the logarithmic expression log9(x316)\log_{9}\left(\frac{x^{3}}{16}\right). The base of the logarithm is 99, and the argument is x316\frac{x^{3}}{16}.
  2. Simplify Logarithm of x3x^3: Recall the logarithm property that allows us to write the logarithm of a quotient as the difference of two logarithms: logb(ac)=logb(a)logb(c)\log_b\left(\frac{a}{c}\right) = \log_b(a) - \log_b(c). Apply this property to the given expression.\newlinelog9(x316)=log9(x3)log9(16)\log_{9}\left(\frac{x^{3}}{16}\right) = \log_{9}(x^{3}) - \log_{9}(16)
  3. Simplify Logarithm of 1616: Now, we can simplify each term separately. Starting with log9(x3)\log_{9}(x^{3}), we can use the power rule of logarithms, which states that logb(ac)=clogb(a)\log_{b}(a^{c}) = c \cdot \log_{b}(a), to simplify this term.\newlinelog9(x3)=3log9(x)\log_{9}(x^{3}) = 3 \cdot \log_{9}(x)
  4. Combine Simplified Terms: Next, we simplify log9(16)\log_{9}(16). Since 1616 is not an obvious power of 99, we cannot directly simplify this term further. So, it remains as log9(16)\log_{9}(16).
  5. Combine Simplified Terms: Next, we simplify log9(16)\log_{9}(16). Since 1616 is not an obvious power of 99, we cannot directly simplify this term further. So, it remains as log9(16)\log_{9}(16).Combine the simplified terms to get the final expression.\newlinelog9(x316)=3log9(x)log9(16)\log_{9}\left(\frac{x^{3}}{16}\right) = 3 \cdot \log_{9}(x) - \log_{9}(16)
