## zakeyadorsey Group Title Simplify 5 log2 k – 8 log2 m + 10 log2 n 2 years ago 2 years ago

1. Eyad Group Title

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

2. Eyad Group Title

Make sense ?

3. zakeyadorsey Group Title

no

4. Eyad Group Title

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 ?

5. zakeyadorsey Group Title

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

6. Eyad Group Title

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: $\LARGE ==> \color{red}{LogX+LogY-LogZ-LogK= \frac{LogX*LogY}{LogZ*LogK}}$
