Question

Simplify 5 log2 k – 8 log2 m + 10 log2 n

Answer 1

First of all use the property :
\[\huge \color{red}{2Logx=Logx^2}\]

Answer 2

Make sense ?

Answer 3

no

Answer 4

Get the number to the log as a power
As an example :
\[\Large \color{blue}{5Log_{2}k=Log_{2}k^5}\]
Can u do that to the rest ?

Answer 5

ok so its log2k^5-log2m^8+log2n^10 but how do i add and subtract this.

Answer 6

Great,So here is another property :
\[\Large ==> \color{orange}{LogX+LogY=Log(X*Y)}\]
\[\Large ==> \color{orange}{LogX-LogY=Log( \frac{x}{y})}\]
If we collect both of them in one question As:
\[\LARGE ==> \color{red}{LogX+LogY-LogZ-LogK= \frac{LogX*LogY}{LogZ*LogK}}\]

Answer 7

ooooh i got it thanks

Answer 8

Yw,Inform me when you need any help :).

Answer 9

ok thanks again
