已知log(2)x=5,log(3)y=-2,求log(6)[3x/4y]...（括弧者为底数）

已知log（2）[log（3)(log(4) x)] = log(3) [log(4) (log(2) y)]=0,求x+y的值 已知log(2){log(3)[log(4)(x)]}=5^0,则x=? 已知log(2)x=5,log(3)y=-2,求log(6)[3x/4y]...（括弧者为底数） 已知0＜a＜1,x=log a 根号2＋log a 根号3y=1/2 log a 5z=log a 根号21 －log a 根号3比较x y z 的大小关系x=log a （根号2）＋log a （根号3）y=1/2 （log a 5）z=log a （根号21） －log a （根号3） log（x+5）=log（x）+log（2） log（8）+log（x）=log（24） 2log（x）=log(2x)+log(3) 若log底数2[log底数3(log底数4)]若log底数2[log底数3(log底数4（x）)]=log底数3[log底数4(log底数2(y))]=log底数4[log底数2(log底数3z)]=0,则x+y+z= 用C语言计算log(5)log(3)-log(2))/sin(π/3)=#include #includeint main(){int a=5,b=3,c=2;double y;y=(log(a)log(b)-log(c))/sin(π/b);printf((log(5)log(3)-log(2))/sin(π/3)=%ld,y);return 0;}x这哪里错了? log 9 X/Y=1/2(log 3 X - log 3 Y) log 9 X/Y=1/4 3log 3 X =2log 3 Y find X and Y 已知log∨a2=x,log∨a3=y ,求a^3x+2y 可以说log a x +log a y=log a log(2x)+log(3y)-log(2z) 怎么化简?log3(x^2-2x-6)=2 log(3x+6)=1+log(x)求解,求每步详...log(2x)+log(3y)-log(2z) 怎么化简?log3(x^2-2x-6)=2 log(3x+6)=1+log(x)求解, [log(4)(2x)][log(2x)(3y)][log(3y)(z)]=log(8x)[(8x)]^2,则z=? 求等式log(2)3*log(3)4*log（4)5*log(5)6*log(6)7*log(7)m=log(3)9时m的值? 已知log（14）7=a log(14)5=b 用ab表示log(35)70=log(3)4*log(4)8*log(8)m=log(4)2 求m log(X+5)+log(X+2)=1 函数y=log(x-3)+log(5-x)的单调递增区间是 函数y=log(1/2)2x+log(1/3)x的单调区间为 log(0.5x)(2)-log(0.5x^3)(x^2)=log(0.5x^3)(4)
