Log Prove

log(b,((sqrt(3)+sqrt(2))/(sqrt(3)-sqrt(2)))=2log(b(sqrt(3)+sqrt(2))

log(b,((sqrt(3)+sqrt(2))/(sqrt(3)-sqrt(2)))

=>(sqrt(3)+sqrt(2))/(sqrt(3)-sqrt(2))........rationalize, multiply (sqrt(3)+sqrt(2))

=((sqrt(3)+sqrt(2))((sqrt(3)+sqrt(2))))/((sqrt(3) - sqrt(2))(sqrt(3)+sqrt(2)))

=(((sqrt(3)+sqrt(2))^2)/((sqrt(3) )^2- (sqrt(2))^2))

=((sqrt(3)+sqrt(2))^2)/(3- 2)

=((sqrt(3)+sqrt(2))^2)/1

=(sqrt(3)+sqrt(2))^2

then

log(b,(sqrt(3)+sqrt(2))^2 =2log(b,(sqrt(3)+sqrt(2))->proven

 

Is it possible for you to use LaTex or write your reply on paper and then upload here for easy reading?

 

manipulate left side



=> rationalize, , multiply by

substitute in log

1. Is this LaTex?

2. If not LaTex, what app did you use to type this reply?

3. Reply using this style of writing from now on. It's a lot easier to read and understand.

 

it's wolframalpha
