@ comingsoon,

- hope this helps ...

Proof for the Power Rule

loga xn nloga x

Proof:

Step 1: 
Let m = loga x

Step 2: Write in exponent form 
x = am

Step 3: Raise both sides to the power of n
xn
 = ( a)n

Step 4: Take log a of both sides and evaluate 
log a xn = log a amn
log a xn = mn log a a
log a xn = mn
log a xn = n loga x

Not sure if this is the way to solve , however trying is not bad.


 


 


logbMr=rlogbM


logbMr=log(M1+M2+M3...+Mr)   //m1,m2,m3 =M ; 1,2,3 represents index  


        =logbM1+logbM2+logbM3+....logbMr


M1, M2, M3 ..Mr represents same variable M there fore the next step is just arithmetic addition, i.e addition of r variable =rx


     =rlogbM

@Black_Panther, Did you only copy paste the solution?
How would it be:
log a xn = log a amn
log a xn = mn log a a

Without actually prooving loga xn nloga x ? It is using the same thing which was actually asked to prove.

@Khairey,

- i knew someone would point that out ... sooner or later ... 
- i think the proof in the VDO does a better job ...

logbMr=log(M1+M2+M3...+Mr)   //m1,m2,m3 =M ; 1,2,3 represents index  



was supposed to be


 


logbMr=log(M1.M2.M3....Mr)   //m1,m2,m3 =M ; 1,2,3 represents index
