已知log2(log3(log4x))=log3(log4(log2y))=0,求x+y的值
已知log2(log3(log4x))=log3(log4(log2y))=0,求x+y的值
已知log2(log3(log4x))=log3(log4(log2y))=0,求x+y的值
有题目可得:
log3(log4x)=1
log4(log2y)=1
又可得到:
log4x=3 x=4^3=64
log2y=4 y=2^4=16
x+y=80
log2(log3(log4x))=log3(log4(log2y))=0,
∴log3(log4x)=log4(log2y)=1,
∴log4x=3,log2y=4
∴x=4^3=64,y=2^4=16
∴x+y=80
log2(log3(log4x)=0
已知log2[log3(log4x)]=0,求x的值
已知Log2[Log3(Log4X)]=0,求X
已知log2[log3(log4x)]=log3[log4(log2y)]=0,求x+y
已知log2(log3(log4x))=log3(log4(log2y))=0,求x+y的值
已知:log2[log3(log4x)]=log3[log4(log2y)]=0 求x+y的值
必修1数学:若log2[log3(log4X)]=0
log2[log3(log4x)]=log3[log4(log2y)]=0求x+y的值,
log2[log3(log4x)]=0求解x值.麻烦写在纸上拍给我.
已知log2(log3(log4x))=0,且log4(log2y)=1.求根号x*y^3/4的值在线等啊.
已知x满足log3(log2x)=1求log4x的值
已知,x满足log3(log2x)=1,求log4x的值?
若log2{log3(log4x)}=0,则x=在百度上找到了一样的题,但回答的我不太清楚。比如说{log3(log4x)}=1 是为什么。
log2(x+1)=log4x解方程
若log2(log3(log4x)=log3(log4(log2y)=log4(log2(log3z)=0则x+y-z=多少我不会打中括号所以就小括号代替了,
已知log2 10=a,log3 10=b 则log3 4等于多少已知log2 10=a,log3 10=b 则log3 4等于多少
已知log3 m=-1/log2 3,则m=
已知log3^(a+1)=2 ,则log2^a=?
