Translate the given logarithmic statement into an equivalent exponential statement. $$\log (a+c)=d$$

Short Answer

Expert verified
Question: Convert the logarithmic statement log(a+c) = d to an exponential statement. Answer: The equivalent exponential statement is $$10^d = a+c$$.

Step by step solution

01

Identify the base, exponent, and the result of the logarithm

In the given logarithmic statement, the base is 10 (since there's no specific base mentioned, we assume it's base 10), the exponent is d, and the result (inside the parenthesis) is a+c.
02

Convert the logarithmic statement to an exponential statement

Using the definition of a logarithm, we can rewrite the logarithmic statement as an exponential statement: $$10^d = a+c$$ Here, 10 is raised to the power of d, and the result is equal to a+c.

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Logarithmic Statements
Understanding logarithmic statements is essential in mathematics, especially when dealing with growth rates and exponential decay. A logarithm tells us the power to which a number must be raised to obtain another number. It is represented by the notation \( \log \) with the number after \( \log \) being the result of the exponentiation, and the base, which is often not written explicitly when it is 10, as the number that is raised to the power. For example, if we have \( \log (a+c) = d \), this statement is telling us that 10 raised to what power gives us \( a+c \)? The answer to that 'what power' is d. This forms the basis for converting from a logarithmic to an exponential statement.

It is crucial to identify correctly the parts of the logarithmic statement. The base, which is often 10 if not specified, since we typically work with base 10 logarithms in a general context; the exponent, which in our case is d; and the result or the number being logarithmized, which is \( a+c \) in this example. Grasping this concept will make the conversion process much simpler.
Exponential Statements
Exponential statements are the inverse of logarithmic statements and involve exponentiation, which means raising a number to a certain power. When converting from a logarithm to an exponential statement, we express the previously implied operation explicitly. Taking \( \log (a+c) = d \), the equivalent exponential statement is \(10^d = a+c\). Here, the base is 10, and it is raised to the power d, resulting in \( a+c \).

In general, an exponential statement with base b, exponent e, and result r would look like \( b^e = r \). Remember, exponential functions are powerful tools in representing continuously growing processes such as population growth or compound interest, and understanding how to express them is fundamental.
Logarithms Without Base
When a logarithm is written without a base, it is understood to be a common logarithm, which means it has a base of 10. This is an important convention to remember when encountering logarithmic expressions in many scientific and mathematical contexts. For instance, \( \log (a+c) = d \) by default is read as \( \log_{10} (a+c) = d \). In general, the common logarithm of a number x is the power to which the base 10 must be raised to obtain that number x.

The absence of a base in a logarithmic statement might lead to confusion, so always remember that a baseless \( \log \) implies a base of 10. It's a shorthand that mathematicians agree on to ease communication. It's particularly important when using logarithmic tables or calculators, which often assume base 10 for \( \log \) buttons or functions.
Exponentiation
Exponentiation is the process of raising a number, known as the base, to a power, known as the exponent. In the exponential statement \(10^d = a+c\), 10 is the base, and d is the exponent. This process defines what is known as an exponential function - a function that increases rapidly as the value of the exponent increases.

Exponentiation is vital for its role in many areas of mathematics, including algebra and calculus, as well as real-world applications such as computing compound interest or describing exponential growth. Understanding exponentiation is also key to mastering the process of converting logarithmic statements to exponential statements, as it helps unveil the operations that logarithms implicitly represent. Furthermore, exploring the properties of exponents, such as \( b^{m+n} = b^m \cdot b^n \) or \( (b^m)^n = b^{mn} \), provides a deeper insight into the nature of exponential relationships.

According to one theory of learning, the number of words per minute \(N\) that a person can type after \(t\) weeks of practice is given by \(N=c\left(1-e^{-k t}\right),\) where \(c\) is an upper limit that \(N\) cannot exceed and \(k\) is a constant that must be determined experimentally for each person. (a) If a person can type 50 wpm (words per minute) after four weeks of practice and 70 wpm after eight weeks, find the values of \(k\) and \(c\) for this person. According to the theory, this person will never type faster than \(c\) wpm. (b) Another person can type 50 wpm after four weeks of practice and 90 wpm after eight weeks. How many weeks must this person practice to be able to type 125 wpm?
