log(a)2 log(a)3等于-2,a值为多少
log(a)2 log(a)3等于-2,a值为多少
log(a)2 log(a)3等于-2,a值为多少
a=5的根号二分之一
log(a)2 log(a)3等于-2,a值为多少
2^(log(2)a)=a,那么2^(-(log(2)a)等于什么?
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)
log a 2/3
log a(2/3)
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)(2/3)
已知log(a)(2/3)
设log(a)2/3下面
已知log(2)^3=a,log(3)^5=b,试用a,b表示log(15)^20
log(2)25×log(3)4×log (5)9等于多少?
(LOG(3,4)+LOG(3,8))(LOG(2,3)+LOG(2,9))等于几 看的懂吧
利用对数的换底公式化简下列 1.log(a)c×log(c)a 2.log(2)3×log(3)4×log(4)5×log(5)2
log(2)(a)=log(3)(b)=log(5)(c)
已知log(3)2=a log(5)2=b用ab表示log(30)90
若log(3)2=a,用a表示代数式log(2)12=?
log(6)2=a,用a表示log(3)6
计算题(log)已知log底数5 ^2=a,log底数5 ^3=b求log底数5根号54 的值
