Write as a Single Logarithm log base 2 of z+2 log base 2 of x+4 log base 9 of y+12 log base 9 of x-2 log base 2 of y

$\log_{2} (z) + 2 \log_{2} (x) + 4 \log_{9} (y) + 12 \log_{9} (x) - 2 \log_{2} (y)$

Step 1

Simplify each term.

Simplify $2 \log_{2} (x)$ by moving $2$ inside the logarithm.

$\log_{2} (z) + \log_{2} (x^{2}) + 4 \log_{9} (y) + 12 \log_{9} (x) - 2 \log_{2} (y)$

Simplify $4 \log_{9} (y)$ by moving $4$ inside the logarithm.

$\log_{2} (z) + \log_{2} (x^{2}) + \log_{9} (y^{4}) + 12 \log_{9} (x) - 2 \log_{2} (y)$

Simplify $12 \log_{9} (x)$ by moving $12$ inside the logarithm.

$\log_{2} (z) + \log_{2} (x^{2}) + \log_{9} (y^{4}) + \log_{9} (x^{12}) - 2 \log_{2} (y)$

Simplify $- 2 \log_{2} (y)$ by moving $2$ inside the logarithm.

$\log_{2} (z) + \log_{2} (x^{2}) + \log_{9} (y^{4}) + \log_{9} (x^{12}) - \log_{2} (y^{2})$

Step 2

Use the product property of logarithms, $\log_{b} (x) + \log_{b} (y) = \log_{b} (x y)$ .

$\log_{2} (z x^{2}) + \log_{9} (y^{4}) + \log_{9} (x^{12}) - \log_{2} (y^{2})$

Step 3

Use the quotient property of logarithms, $\log_{b} (x) - \log_{b} (y) = \log_{b} (\frac{x}{y})$ .

$\log_{2} (\frac{z x^{2}}{y^{2}}) + \log_{9} (y^{4}) + \log_{9} (x^{12})$

Step 4

Use the product property of logarithms, $\log_{b} (x) + \log_{b} (y) = \log_{b} (x y)$ .

$\log_{2} (\frac{z x^{2}}{y^{2}}) + \log_{9} (y^{4} x^{12})$
