Rewrite each equation in exponential form. $$ \log _{p}(z)=u $$

Short Answer

Expert verified
The equation \( \log_{p}(z) = u \) in exponential form is \( p^u = z \).

Step by step solution

01

Understand Logarithmic Form

The given equation is in the form \( \log_{p}(z) = u \). This reads as "the logarithm base \( p \) of \( z \) is \( u \)".
02

Convert to Exponential Form

The conversion from logarithmic to exponential form is based on the definition of logarithms. If \( \log_{b}(a) = c \), then \( b^c = a \). Apply this to the given equation: \( p^u = z \).
03

Write the Exponential Equation

Now we rewrite \( \log_{p}(z) = u \) in exponential form as \( p^u = z \). This is the equivalent statement in exponential form.

Key Concepts

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

Logarithmic Form
The logarithmic form is a mathematical representation that describes the relationship between three numbers. It is used extensively in various areas of mathematics including algebra and calculus. In the equation \( \log_{p}(z) = u \), the logarithmic form is expressed with a base, which in this case is \( p \), a result, which is \( u \), and an argument that is \( z \). This can be verbally presented as "\( u \) is the power to which the base \( p \) must be raised to yield \( z \)". Understanding this structure is key to solving problems that involve conversion between logarithmic and exponential forms.
  • Base: \( p \)
  • Argument: \( z \)
  • Result: \( u \)
With these components in mind, the logarithmic form helps simplify the process of solving exponential equations.
Conversion
Conversion between logarithmic and exponential forms is a mathematical technique that allows us to express equations in different but equivalent ways. This process is grounded in the definition of logarithms, which states that if \( \log_{b}(a) = c \), then it implies \( b^c = a \). This is the fundamental principle behind converting a logarithm into an exponent.To understand conversion:- Recognize the given logarithmic statement: \( \log_{p}(z) = u \).- Apply the conversion rule: \( p^u = z \).This transformation does more than just restate a problem; it changes the form to make it potentially more solvable in particular contexts or to express the same relation differently. Conversion is a powerful tool in mathematics for dealing with both abstract and practical problems.
Base of Logarithm
The base of a logarithm is a pivotal element that defines how the relationship is structured in both the logarithmic and exponential forms. In \( \log_{p}(z) = u \), the base is \( p \). This base dictates the scale of progression of the logarithmic equation under consideration.When converting to exponential form, the base \( p \) remains the factor that undergoes exponentiation. For example, converting \( \log_{p}(z) = u \) into \( p^u = z \), we see that \( p \) remains consistent as the base that is raised to the power of \( u \) to achieve the result \( z \).Understanding the base of a logarithm is crucial because:
  • It determines the rate at which the power increases.
  • In practical applications, different bases can represent various systems of measurement (e.g., base 10 for decimal systems, base 2 for binary systems).
The comprehension of the base in logarithms is fundamental to accurately converting and manipulating such expressions.
Exponential Equation
An exponential equation is one where a number, called the base, is raised to a particular power, generating a result. Exponential equations are at the core of representing growth patterns and natural processes in real-life scenarios. In the context of converting the logarithmic expression \( \log_{p}(z) = u \) to an exponential form, we derive the exponential equation \( p^u = z \). This equation now states that the base \( p \), when raised to the exponent \( u \), equals \( z \).Characteristics of exponential equations:
  • They often model exponential growth or decay (like interest compounding, population growth, radioactive decay).
  • The base signifies the growth factor in such models.
Exponential equations are significant both mathematically and in application to solve complex problems and represent dynamic relationships in a simpler, straightforward form. Understanding how to convert and work with these equations is a critical skill in mathematics.
