Which is 3 logx + 4 log(x-2) written as a single logarithm?
fomenos

Answer:

The answer is 12\log{(x(x-2))}

Step-by-step explanation:

Exponential property of logarithm:

We have that:

a \log{x} = \log{x^{a}}

Sum of logarithms:

We have that:

\log{a} + \log{b} = \log{ab}

Applying the exponential property:

3\log{x} = \log{x^3}

4\log{(x-2)} = \log{(x-2)^4}

So

3\log{x} + 4\log{x-2} = \log{x^3} + \log{(x-2)^4}

Additive property

\log{x^3} + \log{(x-2)^4} = \log{x^3(x-2)^4} = \log{(x(x-2))^12}

Exponential property:

\log{(x(x-2))^12} = 12\log{(x(x-2))}

The answer is 12\log{(x(x-2))}

5,000 because a coin has 2 sides so there is 50% chance flipping on tails.
