Discussion Overview

The discussion revolves around solving logarithmic equations and understanding properties of logarithms, specifically focusing on the expressions 3log_6 - log_6 12 + log_6 2 and log_x 4. Participants seek help with calculations and concepts related to logarithmic functions, including vertical asymptotes, x-intercepts, range, and domain.

Discussion Character

  • Homework-related
  • Mathematical reasoning
  • Technical explanation

Main Points Raised

  • One participant asks for the solution to the expression 3log_6 - log_6 12 + log_6 2.
  • Another participant provides properties of logarithms, including the product, power, and quotient rules.
  • A participant introduces the change of base formula for logarithms, stating log_4 x = ln x / ln 4.
  • There is a discussion about the equivalence of the expressions y = log_4 x and x = 4^y, leading to further exploration of logarithmic properties.
  • Participants express confusion about the notation log_x 4, with one questioning how to interpret it when x is the base.
  • Another participant suggests that if x is a given number, log_x 4 can be calculated as (log 4) / (log x), with flexibility in the choice of logarithmic base.
  • There is a request for clarification on finding the domain, range, and x-intercept for the function y = log_x 4.

Areas of Agreement / Disagreement

Participants express varying levels of understanding and confusion regarding the logarithmic expressions and their properties. There is no consensus on the solutions or interpretations of the problems presented.

Contextual Notes

Some participants appear to have different interpretations of the notation log_x 4, leading to uncertainty in the discussion. The exploration of logarithmic properties is not fully resolved, and assumptions about the values of x are not clarified.

Who May Find This Useful

Students or individuals seeking assistance with logarithmic functions, properties of logarithms, and related mathematical concepts may find this discussion relevant.

whats the answer to dis one?helppppppppppppp!

3log_6 - log_6 12 + log_6 2 = ? (the base is 6)





whats the vertical asymptote, x-intercept, range and domain for this one -
log_x 4
 
Mathematics news on Phys.org
Use the basic properties of logarithms:

log_b(xy) = log_b(x) + log_b(y)
log_b(x^y) = y log_b(x)
log_b(x/y) = log_b(x) - log_b(y)
 
As for the second,use

[tex]\log_{4}x=\frac{\ln x}{\ln 4}[/tex]

how did u get dat?
logx4 = In x/In 4??

Saying "y= log4 x" is the same as saying "x= 4y". Now take the logarithm (with whatever base you want- log10 or ln if you want to use a calculator): log x= log 4y[/sup= y log 4 so y= log x/log 4.
 
helllooooooooooooooo

x is the base not 4, logx4,, how oh how do u?

What do you want to do with logx 4? If you x is a given number, then you would find logx4, just as before: (log 4)/(log x). Again, the log can be either base 10 or natural log whichever is easier.
 
yooooooooooo help
