计算log9底8分之log3底2
计算log9底8分之log3底2
(log3 4+log3 8)(log2 3+log2 9)+(log3 根号2)(log9 7)/(log1/3 7)
由换底公式怎么得到log9(x+5)=log3[2(x+5)]=1/2log3(x+5)
[log4(3)/log4(8)][log3(2)log9(2)]
(log2(3)+log8(9))x(log3(4)+log9(8)+log3(2))
(log2 3+log8 9)(log3 4+log9 8+log3 2)的运算过程
计算:(log4 9+log8 3)(log3 2+log9 2)-log1/3 4√81
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 5-log3 15+1/2log9 27 的值
求x,y值.6log9^x+3log27^y=8log3^x+2log9^y=2
1.log2 3*log3 4*log4 5*log5 2 2.(log4 3+log8 3)8(log3 2+log9
计算(log4 3+ log8 3)(log3 2+ log9 2)-- log1/2 32^(1/3)+5^(log2
