In summary, the conversation involved discussing the best approach for solving a math problem involving logarithms. The suggestion was made to divide 343 by 7 and then use the factoring trick to find the solution without needing to use logarithms. The conversation then turned to the importance of knowing math skills and the idea that once the mind is exposed to a new idea, it cannot go back to its original dimension.

I say we take the log on both sides as step one.

Yes?

The first thing I would do is start dividing 343 by 7! 343- 40(7)= 343- 280= 63= 9(7) so \(\displaystyle 343= 7(49)= 7(7)(7)= 7^3\). \(\displaystyle \sqrt{343}= 7^{3/2}\) so \(\displaystyle 7^{2n}= 7^{3/2}\) so \(\displaystyle 2n= 3/2\), n= 3/4.

No logarithms necessary!

Nicely done! It pays to know math tricks.

Beer soaked non sequitur ramblings follow.

A man's mind stretched by a new idea can never go back to its original dimension.

I don't think I would consider factoring a "trick".

I meant to say skill not trick.
