AI Thread Summary
The discussion revolves around evaluating and simplifying a logarithmic expression without a calculator. The initial steps involve combining logarithms and applying the laws of logarithms, leading to the expression 3 / log2(10). However, a notation error is identified in the simplification process, where the correct interpretation of the fraction is clarified. Participants emphasize the importance of proper notation in mathematical expressions to avoid confusion. Overall, the conversation highlights the need for accuracy in both calculations and notation when solving logarithmic problems.

Hi, I have a log problem. Can anyone please check if I did it correctly!?

Homework Statement


Evaluate the following using the laws of logarithms.
Simplify your answer as much as possible. (Note:
These should be done without a calculator).

[log(5)+log(2)] / log2(cubic root of 10)
= log(5*2) / log2 (10)1/3
= log(10) / 1/3*log2(10)
= 3 / log2(10)


Is this simplified correctly? Can we simplify more?

Good.
 
Thank you!
 
Know this: Your notation is faulty near the end of your steps.

This, "= log(10) / 1/3*log2(10)" is not what you meant.
You really meant and should have written, log2(10)/(1/3)*log2(10)
 
That is because 1/ab is normally read as 1/(ab), not as (1/a) b.
 
Yes, that what I meant symbolipoint. Thank you everybody! I need to pay more attention on how I write it properly.
