若log9x*log43=(log34+log43)^2-(log43/log34+log34/log43),则x=多少若log9x*log43=(log34+log43)^2-(log43/log3

若log9x*log43=(log34+log43)^2-(log43/log34+log34/log43),则x=多少
若log9x*log43=(log34+log43)^2-(log43/log34+log34/log43),则x=多少

若log9x*log43=(log34+log43)^2-(log43/log34+log34/log43),则x=多少
log9x*log43=(log34+log43)^2-(log43/log34+log34/log43)
log9x*log43=(log34)²+(log43)²+2-[(log34)²+(log43)²]
log9x*log43=2
log9x=2log34
1/2log3x=log3 16
x^(1/2)=16
x=256
