write each equation in its equivalent logarithmic form. $$5^{-3}=\frac{1}{125}$$

Short Answer

Expert verified
So, the logarithmic form of the equation \(5^{-3}=\frac{1}{125}\) is \(\log_5 \frac{1}{125} = -3\).

Step by step solution

01

Identifying the Base, Exponent, and the Result

In the given exponential equation \(5^{-3}=\frac{1}{125}\), the base \(a\) is 5, the exponent \(b\) is -3, and the result \(c\) is \(\frac{1}{125}\).
02

Converting to Logarithmic Form

Using the rule that states the exponential form \(a^b = c\) is equivalent to the logarithmic form \(\log_a c = b\), the equation can be converted to \(\log_5 \frac{1}{125} = -3\).

Key Concepts

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

Exponential Equation
An exponential equation is a mathematical expression where a number, known as the base, is raised to a power, called the exponent. This type of equation often describes how quantities grow or decay rapidly. For example, in the equation \(5^{-3} = \frac{1}{125}\), the base is 5, the exponent is -3, and the result is the fraction \(\frac{1}{125}\). This tells us that 5, when multiplied by itself three times in a manner described by the exponent, results in \(\frac{1}{125}\). Turning an exponential equation into a different form, like a logarithmic equation, helps in solving problems related to growth, decay, and half-life calculations. Such transformations often simplify complex calculations, making them more manageable. Understanding exponential equations is fundamental in algebra and calculus, especially in fields that handle rates of change, such as biology, physics, and finance.
Base and Exponent
In any exponential equation, the base and exponent play crucial roles. The base is the number that is repeatedly multiplied by itself, and the exponent tells us how many times to multiply that base. For instance, in \(5^{-3}\), 5 is the base and -3 is the exponent. When the exponent is negative, as in this example, it indicates the reciprocal of the base raised to the corresponding positive exponent. Thus, \(5^{-3}\) can be expressed as \(\frac{1}{5^3}\), yielding \(\frac{1}{125}\) as the result.The concept of base and exponent helps us understand operations involving powers, roots, and reciprocals. These fundamentals are vital in advancing mathematical skills, ensuring accurate problem solving, and establishing a foundation for learning higher-level algebra, calculus, and beyond.
Converting Equations
Converting between exponential and logarithmic equations is an essential skill often used to simplify complex mathematical expressions. This conversion process involves understanding the relationship between exponents and logarithms.The equation \(a^b = c\) can be converted into its equivalent logarithmic form \(\log_a c = b\). This transformation allows mathematicians and scientists to solve for variables with greater ease. For the given equation \(5^{-3} = \frac{1}{125}\), it is converted into the logarithmic form \(\log_5 \frac{1}{125} = -3\).This conversion is particularly useful when dealing with problems where the exponent is an unknown. Logarithmic equations are often easier to manipulate algebraically, providing a clear path to solutions. Mastering this process improves the ability to tackle various mathematics problems, from basic arithmetic to advanced calculus and engineering mathematics.

By 2019 , nearly 1 dollar out of every 5 dollars spent in the U.S. economy is projected to go for health care. The bar graph shows the percentage of the U.S. gross domestic product (GDP) going toward health care from 2007 through 2014 , with a projection for 2019.(GRAPH CAN'T COPY). The data can be modeled by the function \(f(x)=1.2 \ln x+15.7\) where \(f(x)\) is the percentage of the U.S. gross domestic product going toward health care \(x\) years after \(2006 .\) Use this information to solve. a. Use the function to determine the percentage of the U.S. gross domestic product that went toward health care in \(2009 .\) Round to the nearest tenth of a percent. Does this underestimate or overestimate the percent displayed by the graph? By how much? b. According to the model, when will \(18.5 \%\) of the U.S. gross domestic product go toward health care? Round to the nearest year.
