Hello again!
I have been working on this log, and the longer I work on it, the more confused I get! Here's the problem:
Find the exact value for:

[tex]ln(ln[e^{e^{5}}[/tex]])

----
Here's what I've tried so far:

[tex]e(ln[e^{e^5}}[/tex]])

[tex]e^{x} = ln(e^{e^5}}) [/tex]
[tex]e^{x} = e^{e^5}}[/tex]
[tex]e^{5} = (2.72)^{5}[/tex]
[tex]e^{x} = e^{149}[/tex]
[tex]x = 149 [/tex]

...I have no idea if I'm doing this right, but I'm not feeling like I am...Help?

use the property that Ln(a^b) = b Ln(a), Ln(e) = 1, Ln(e^a) = a
 
  • #3
z=ln(lne^(e^5)). Use the definition of a log now.
 

FAQ: Solving Logarithm Overkill: Find Exact Value for ln(ln[e^{e^{5}}])

What is a logarithm and how does it relate to ln?

A logarithm is a mathematical function that calculates the power to which a given number (called the base) must be raised to produce a given number. The natural logarithm, ln, is a special type of logarithm with a base of e, which is a mathematical constant approximately equal to 2.718.

Why is it important to solve for the exact value of ln(ln[e^{e^{5}}])?

Solving for the exact value of ln(ln[e^{e^{5}}]) allows us to understand the relationship between exponential and logarithmic functions, and to accurately calculate values in complex mathematical expressions.

What is the process for solving ln(ln[e^{e^{5}}])?

The process for solving ln(ln[e^{e^{5}}]) involves using the properties of logarithms to simplify the expression. First, we can use the fact that ln(e^{x}) = x to rewrite the expression as ln(ln(e^{5})). Then, we can use the same property again to simplify further to ln(5). Finally, we can use the definition of ln to find the exact value of ln(5), which is approximately 1.61.

Can ln(ln[e^{e^{5}}]) be solved without a calculator?

Yes, ln(ln[e^{e^{5}}]) can be solved without a calculator by using the properties of logarithms and the definition of ln. However, the exact value may be difficult to calculate by hand, so a calculator may be useful for finding the final numerical value.

How can understanding logarithms and their properties help in real-world applications?

Logarithms and their properties are used in a variety of fields, including finance, science, and engineering. They can be used to model exponential growth and decay, calculate interest rates, and solve problems involving complex mathematical expressions. Understanding logarithms can also help in interpreting data and making predictions in fields such as epidemiology and demography.
