已知log(a)(2)=m,log(a)(3)=n.则a^(2m+n)的值为多少?
已知log(a)(2)=m,log(a)(3)=n.则a^(2m+n)的值为多少?
已知log(a)(2)=m,log(a)(3)=n.则a^(2m+n)的值为多少?
log(a)(2)=m得a^m=2,a^2m=2^2=4;
log(a)(3)=n得a^n=3
由指数运算可加性得(a^2m)*(a^n)=a^(2m+n)=12
12
log(a)M+log(a)N=?
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
已知log(a)(2)=m,log(a)(3)=n.则a^(2m+n)的值为多少?
已知log右下角a 2=m,log右下角a 3=n.求a的m+n次方
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)
证明a(log(m)n)=n(log(m)a)
log a (m^n)=(log a m)^n?
求证 log(a) (M·N)=log(a) M+log(a) N
log(下标a)(M*N)是什么意思?= log(下标a)M+log(下标a)N
已知log a (xy)==√2,log a (ay)=2 求log a x的值
log(a)(mn)=log(a)(m)+log(a)(n)为什么呀?
已知a^2=m,a^3=n,a>0且a≠1,求2log a m+log a n
已知log(2)3=a,log(3)7=b试用a,b表示log(2)14
已知log(2)3=a,log(3)7=b,试用a,b表示log(14)56
已知log(2)^3=a,log(3)^5=b,试用a,b表示log(15)^20
已知log(8)27=a,求log(6)16
已知Log( 12)27=a ,求Log( 6 ) 16
可以说log a x +log a y=log a
