Step 1.1

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

$2 \log (2 x y) - (\log (3) + 2 \log (5))$

Step 1.2

Simplify $2 \log (2 x y)$ by moving $2$ inside the logarithm.

$\log ({(2 x y)}^{2}) - (\log (3) + 2 \log (5))$

Step 1.3

Use the power rule ${(a b)}^{n} = a^{n} b^{n}$ to distribute the exponent.

Step 1.5.1

Simplify $2 \log (5)$ by moving $2$ inside the logarithm.

$\log (4 x^{2} y^{2}) - (\log (3) + \log (5^{2}))$

Step 1.5.2

Raise $5$ to the power of $2$ .

$\log (4 x^{2} y^{2}) - (\log (3) + \log (25))$

Step 1.6

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

$\log (4 x^{2} y^{2}) - \log (3 \cdot 25)$

Step 1.7

Multiply $3$ by $25$ .

$\log (4 x^{2} y^{2}) - \log (75)$

Step 2

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

$\log (\frac{4 x^{2} y^{2}}{75})$
