log【2】(log【8】m)=log【8】（log【2】m）,求（log【2】m）的平方【】内为底log【2】(log【8】m)=log【8】（log【2】m）,求（log【2】m）的平方【】内为底

log【2】(log【8】m) =log【8】（log【2】m）,求（log【2】m）的平方【】内为底
log【2】(log【8】m) =log【8】（log【2】m）,求（log【2】m）的平方【】内为底

log【2】(log【8】m) =log【8】（log【2】m）,求（log【2】m）的平方【】内为底
8=2^3,所以log【8】m=三分之一log【2】m
设log【2】m=x
所以log【2】(三分之一x）=三分之一log【2】x,所以三分之一x=x^3,因为x>0,
所以三分之一=x^2,所以（log【2】m）的平方=1/3

log【2】(log【2】m^1/3) =log【2】（log【2】m）^1/3
log【2】m^1/3=（log【2】m）^1/3
1/3*log【2】m=（log【2】m）^1/3
1/3*(log【2】m)^2/3=1
(log【2】m)^2=3^3=27
（log【2】m）的平方=27

8^[log【2】(log【8】m)]=8^[log【8】（log【2】m）]
(log【8】m)^3=log【2】m
8^(log【8】m)^3=8^[log【2】m]
8^[log【8】m*[log【8】m]^2]]=2^[3*log【2】m]
m^[log【8】m]^2]=m^3
[log【8】m]^2=3
