log2/27及log3=alog5=blog2/27及log3=alog5=blog2/27及log3=alog5=blog2/27=log2-log27=log(10/5)-log(3^3)=lo
log2/27及 log 3=a log5=b
log2/27及 log 3=a log5=b
log2/27及 log 3=a log5=b
log2/27=log2-log27=log(10/5)-log(3^3)=log10-log5-3log3=1-b-3a
log2/27及 log 3=a log5=b
已知log2=a及log 3=b,以a及b表示log2/27.
log(27)16/log(3)4=
log数学题,求救!高中水平就可以!log(x+8)-log2=log(3x+2)求x.
解方程 log2(x+14)+log(x+2)=log(x+6)+3
y=log2(sinx+3)的值域log后的2在log下面
a=2^0.6,b=logπ(3),c=log2(sin2),则比较大小
已知log(8)27=a,求log(6)16
已知Log( 12)27=a ,求Log( 6 ) 16
log(2)3=a,则log(6)4=(
可以说log a x +log a y=log a
对数函数题 log a - log b = 3 log (c/2) 求 a = ______________
log(a)M+log(a)N=?
已知a的二分之一次方等于4/9,则log2/3(在log右下方)a=
log a 2/3
log a(2/3)
log(27)32 × log(64)27+log(9)2 × log(4)根号27=?log(27)32 × log(64)27+log(9)2 × log(4)根号27=?
证明对数运算法则(1)log(a)(MN)=log(a)(M)+log(a)(N); (2)log(a)(M/N)=log(a)(M)-log(a)(N);(1)log(a)(MN)=log(a)(M)+log(a)(N); (2)log(a)(M/N)=log(a)(M)-log(a)(N); (3)log(a)(M^n)=nlog(a)(M) (n∈R)
