pls explain further i dont really understand this

If given log m raise to the power n then power comes before log. (i.e) we can write it as : n log m. 
Gourav said: (Sep 28, 2013)  
Property of log is used i.e log m raise to power n miss @Shalimi is right. Work on some more problem on log like change of base formula which is very high end.

Can we cut log 8 from the denominator and numerator? referring to last step. 
Ramme said: (Sep 5, 2014)  
Why we can't put like this log 8 = log root(8) * log root(8) ? 
RUHUL AMIN AHMED said: (Oct 20, 2014)  
We know that, log(8)^1/2 = log8/2. So, answers is 1/2.

2 log 15/2log 25/81+3 log 2/9 = log2 solve.

@Rahul Amin Ahmed. log 8^(1/2) = not log8/2.

What is antilog? 
Dishallar said: (Jun 29, 2016)  
Please help me with these logarithms given that log 3 = M. a) m+n as a logarithm of single number. b) log 9 in terms of m. c) log2 1/4 interms of m&n. 
Dishallar said: (Jun 29, 2016)  
Given that log 2= 0,3010 and 3 = 0,4771. Evaluate, a) Log 2, 25. b) Square root of log 60.

2 concept goes here. 1. You can write root 8 in terms of power i.e 8^(1/2) then 1/2 is multiplied and now the term is (1/2)log8/log8 here many people think that log8/log8 cancel but this thing doesn't happen log cannot be cancelled. So we have to use the formula i.e, loga/logb i.e log(ab) so here log( 88) gives the result log0 and value of log 0 is 1 so when 1 is multiplied with 1/2 it is 1/2.

Thank you all for explaining it.

=Log√8/Log8. =0.4515/0.9030, =0.5, =1/2. 
Ajith said: (Jan 16, 2021)  
Log √8 divided by 8. There is a formula i.e. Log a divided by log b can be written as log a base b. Here , Since the bases of loga and logb are same so we can write log a base b. So, log root 8 divided by 8 can be written as log root 8 base 8, So, implies root 8 can be written as 8 power 1/2, So, low 8 power 1/2 base 8 is equal to 1/2. 
India said: (May 17, 2021)  
Log root 8/log 8= Log root 8/log root 8 (root 8) Log and log cancels and also root 8 and root 8 cancels. Then 1 in the numerator and root 8 in denominator remains, Hence 1/root 8 is the answer.
