若log底数2[log底数3(log底数4)]
问题描述:
若log底数2[log底数3(log底数4)]
若log底数2[log底数3(log底数4(x))]=log底数3[log底数4(log底数2(y))]=log底数4[log底数2(log底数3z)]=0,则x+y+z=
答
∵log底数2[log底数3(log底数4(x))]=log底数3[log底数4(log底数2(y))]=log底数4[log底数2(log底数3z)]=0,∴log底数3(log底数4(x))=log底数4(log底数2(y))=log底数2(log底数3z)=1,∴log底数4(x)=3log底数2(y)=4lo...
