设a=0.1的0.9次方b=3.2的0.4次方c=log(5.2的0.6次方),比较大小设a=0.1的0.9次方b=3.2的0.4次方c=log(5.2的0.6次方),比较大小设a=0.1的0.9次方

设a=0.1的0.9次方 b=3.2的0.4次方 c=log(5.2的0.6次方),比较大小
设a=0.1的0.9次方 b=3.2的0.4次方 c=log(5.2的0.6次方),比较大小

设a=0.1的0.9次方 b=3.2的0.4次方 c=log(5.2的0.6次方),比较大小
a=0.1^0.9<1
b=3.2^0.4>1
c=log5.2(0.6)<0
故有b>a>c

a=0.1^0.9 lga=0.9*lg0.1=-0.9<0, 0b=3.2^0.4 lgb=0.4lg3.2>0 b>1
c=log(5.2 0.6)<0
b>a>c
