log3 x=1 log16 64=x logx 1/5=-1/4 log32 x=7/5 logx 234=5/6 log125 1/25=x
log3 x=1 log16 64=x logx 1/5=-1/4 log32 x=7/5 logx 234=5/6 log125 1/25=x
1,x=3^1=3
2,x=log[2^4] 2^6=6/4=1.5
3,1/四次根号x=1/5,所以,x=5^4=625
4,x=32^(7/5)=(2^5)^(7/5)=2^(5*7/5)=2^7=128
5,x^(5/6)=234,所以,x=234^(6/5)
6,x=log[5^3] 5^(-2)=-2/3
一般对于log[x^a] y^b=b/a*log[x] y
(1)x=3
(2)x=1.5
(3)x=625
(4)x=128
(5)x=234^(6/5)=696.7212054
(6)x=-2/3
log3 x=1 log16 64=x logx 1/5=-1/4 log32 x=7/5 logx 234=5/6 log125 1/25=x
