化简log2[log3(log5 125)]……
1.化简log2[log3(log5 125)]
2.5log2(log9 81)
3.log9 4 +log3 8 /log1/3 16
4.求值(lg2)^2+两个2*lg5+lg50
3.log9 4 +log3 8除以log三分之一 16
4.求值(lg2)平方+lg2乘以lg5+lg50

1、log5 125=3,原式=0
2、log9 81=2,原式=5
3、4、题目看不懂...

化简log2[log3(log5 125)]…… (log2)和(log3)变成(log5) log2 25*log3 4 *log5 9 计算log2 6-log2 3,lg5+lg2,log5 3+log5 1/3,log3 5-log3 15 (log3^4+log5^2)(log2^9+log2^根号3) log2(a)=log3(b)=log5(c) 高中数学题log2^25 * log3^4 * log5^9 log2 25 乘以log3 4 乘以log5 9 若log2(x)=log3(y)=log5(z) log2(3)*log3(5)*log5(8)（具体步骤） log2^25*log3^2倍根号2*log5^9= log2 5*log5 81*log3 4+ln根号e
