-5log9 4+log3 32/9-5^log5 3-(1/64)^-2/3
-5log9 4+log3 32/9-5^log5 3-(1/64)^-2/3
=-5lg4/lg9+lg32/9/lg3-3-64^2/3
=-5lg2/lg3+(5lg2-2lg3)/lg3-3-16
=-5lg2/lg3+5lg2/lg3-2lg3/lg3-3-16
=-2-3-16
=-21
-5log9 4+log3 32/9-5^log5 3-(1/64)^-2/3
计算:-5log9^4+log3^32/9-5log5^3-(1/64)^-2/3
|log3(5)-2|+log9(25)+(1/32)^1/5
计算[log9(5)+log3(5)]乘[log25(3)+log125(9)]
5log9 4 + log3 32/9 - 5的log5 3次方 - (1/64)的-2/3次方
-5log9(4)+log3(32/9)-(1/64)^(-2/3),怎么化简,要步骤谢谢.RT
log3*2/log9*4
已知log3(4)=a,log3(5)=b 则log9(16/25)=
已知log3(4)=a,log3(5)=b 则log9(16/25)=
log3 5-log3 15+1/2log9 27 的值
-5log9为底4的对数+log3为底(32/9)的对数-5^(log5为底3的对数)-(1/64)^(-2/3)
(log4 3+log8 3)(log3 2+log9 2)-log1/2 32^1/3+5^(log25 9)
化简(log3 4)/(log9 8)
log3*2/log9*4=?
4log9为底 2的对数-log3为底 32/9的对数+log3为底 8的对数-5的2倍log以5为底3的对数 =多少?
log3(x-1)=log9(x+5)怎么解?RT,3和9是底数..
log9^5=a,log3^7=b,求log35^9=?
若log9 5=a,log3 7=b,则log35 9=______.
