Answer:

The error is in step 3. You cannot use a property of logarithms to prove that same property.

Step-by-step explanation:

Here we  the proof of the quotient rule as

If Logₐx = M and Logₐy = N

Then x = a^M and y = a^N

x ÷ y = a^M ÷  a^N = a^{(M-N)}

Take log of both sides we get

Logₐ(x÷y) = Logₐa^{(M-N)}

Logₐ(x÷y) =M-N logₐa

Logₐ(x÷y) =M-N

∴Logₐ(x÷y) = Logₐx - Logₐy

In properties of logarithms, what is log2 25?
spayn [35]
log_a(b)=clog_a(b)=c translates to

a^c=ba^c=b
let's say it equals y

log_2(25)=ylog_2(25)=y
trsnaltes to
2^y=252^y=25
doesn't help us
we can also translate it to
log_2(5^2)log_2(5^2) or 2log_2(5)log_2(5^2)
