Logarithm Change of Base Formula & Solving Log Equations - Part 1 - [7]

In this lesson, you will learn how to solve logarithmic equations by using the log change of base formula. We will learn that we can express the logarithm in terms of a different log with a different base. This is very useful when we solve logarithmic equations because we can construct the proper log to cancel terms and isolate the variable that we are trying to solve. In this lesson, we will introduce the log change of base formula and apply it to solving equations that contain logarithms.

I bought his CD in 2007 when I was in community college 😊 and surly I passed with an A he is awesome 👏

Great teacher - wish I'd had you during my studies!

6:20 - Finally. Thank you for giving this part here. Literally the only question I had about this, is whether the base is fixed to 2 or 10 or not.
But now thanks to you, I have finally no doubts.

I'm happy with that proof, since I was struggling at.
Logarithm of 1 is always zero irrespective of the bases.
Logarithm to base 1 is undefined.
E.g log 2 = log 2/log 1 =
log 2/0 = undefined.

Respected teacher you toght so well with kond heart. Thank you.

[lilbunnyjk]

I was struggling with that prove that how should I prove this sir u r superb ...thanks for this 💕

[pekkagronfors]

I write a lot of Powershell scripts at work. They are often not very mathematically intensive, but on a few occasions your videos have saved my day. Thank's.

[NikitaNewa]

This lesson is amazing and well understood please can you do a lesson on proving rational and irrational numbers please

[kaili]

I understand the last derivation. Wow~ I used to get confused with them. Thanks.
