# Solving Equations with Logarithms Pt 1

PLEASE NOTE my last reply at 10:26 must be 3.968. There’s an annotation correction however you’ll be able to solely see this if utilizing FLASH.

In a 3 half video I do many examples of fixing equations utilizing logarithms to maneuver the variable out of the exponent. Partly two we take away logarithms from the equation to unravel for X.

Listed below are my different PreCalculus classes involving Logarithms

Thankyou thank you thank you . You teach better then my teacher

6:22 we can directly write this eqn in log form i.e

Log 41 = x

Applying our common sense and basic rule of log

We don't need to do what he did

i love you thank u

This man's penmanship has FLAWLESS fluidity. I love looking at it!

Thank you

So how can the base just disappear?

47 who disliked the videos are actually the dumb ones in class

I thought you were writing reeeeally fast. Then I realised I'm watching at 1.5x speed.

nice example

THANK YOU!!!!

yo youtube is getting a little out of hand with these adds

Why am I watching this if I'm doing calculus LOL

first online person i can understand with this

wonderful video. I enjoy your lively attitude while you teach, it keeps me engaged.

Your handwriting rocks, sir😍

Mr.RobBob can you help me!! How do you solve a exponential equation with a base of 1!

Dude, you're the best. I literally only watch your videos.

Hi. When I punch in (ln(2711) + 4) divided by 3 I get 3.96835… can you tell me what I'm doing wrong? You got 2.64.

Thank you for your help and enthusiasm. I normally don't subscribe to people, but since teachers don't make nearly what they deserve, I though, "What the hell, he deserves it." Oprah should interview you and the Khan dude.

You've been my professor for two years now.

Hey Mr. Tarrou can you explain how to get 10^x = e^2x-1

It's kind of hard for me.

entry was superb. good handwriting

sorry but…i learned it 15age i'm korean..

You rock!
