化简(log3 4)/(log9 8)
(log3 4+log3 8)(log2 3+log2 9)+(log3 根号2)(log9 7)/(log1/3 7)
(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
1.log2 3*log3 4*log4 5*log5 2 2.(log4 3+log8 3)8(log3 2+log9
(log2 3+log4 27)*(log3 4+log9 8)=
化简(log4(3)+log8(3))(log3(2)+log9(2))
[log4(3)/log4(8)][log3(2)log9(2)]
计算log9底8分之log3底2
[log2(3)+log4(9)][log3(4)+log9(2)]等于
(log3^2 + log9^4)×(log4^3 + log8^3)
计算题:(log2的次方+log8 9的立方)(log3 4的立方+log9 8的立方+log3 2的立方)
求x,y值.6log9^x+3log27^y=8log3^x+2log9^y=2
