Logarithmic Equations

To solve a logarithmic equation, rewrite the equation in exponential form and solve for the variable.
Example: if log₂x=3, in exponetial form: 2³=x. therefore x = 8
To Check: You can substitute x=8 in the main equation to find out if it true.
log₂8 = 3

[LUCKYSINYINZA-cdpk]

Mr sir you teach ver well (excellent presentation) but I don't understand where (1/2) to the power 3 came from on equation 3

[justinabello]

I m not getting this example u are solving

[ezepaul]

Please sir

You are awesome sir thank you, and then how can someone solve this log10(2x+1)-log10(3x-2)=1

[ndasindum]

Thank you sir.please I have A question can I ask

[koffisiekouadiocharles]

Sir plus i don't understand thé way you did it in thé first question, you will not cross multiply

[BaahKwaku-dsnk]

Pls i want to teach probability repllacement and without replacement

[portiadzah]

Infact you teach very well but it’s not every step that you explain. The question 3 u did some calculations to make the fraction go but didn’t explain that point, where the 1/2 came from???

[AzavuGloria]

Sir please I just joined your class
Please the first question how do we get x²=x squared=3x+2 how do we get the +2

[JoshuaNuma]

Pls
why did you divide it by -x² in question 2

[lameckkasalika]

Question 2 how did you come up with the negative x squared 🤔 towards the end
