Which expression is equivalent to log3(x + 4)?
dangina [55]

Answer:

log[3(x+4)] is equal to log(3) + log(x + 4), which corresponds to choice number three.

Step-by-step explanation:

By the logarithm product rule, for two nonzero numbers a and b,

\log{(a \cdot b)} = \log{(a)} + \log{(b)}.

Keep in mind that a logarithm can be split into two only if the logarithm contains the product or quotient of two numbers.

For example, 3(x + 4) is the number in the logarithm \log{[3(x + 4)]}. Since 3(x + 4) is a product of the two numbers 3 and (x + 4), the logarithm \log{[3(x + 4)]} can be split into two. By the logarithm product rule,

\log{[3(x + 4)]} = \log{(3)} + \log{(x + 4)}.

However, \log{(x + 4)} cannot be split into two since the number inside of it is a sum rather than a product. Hence choice number three is the answer to this question.

Brums [2.3K]
While Gary is using an indirect method to prove that segment DE is not parallel to segment BC in the triangle ABC shown ( I attached below the picture that should have support your question). And If he starts with the assumption that segment DE is parallel to segment BC I am pretty sure that <span>inequality which he will  use to contradict the assumption is the first option : </span><span>4:10 ≠ 6:14</span>
