2log5(25)-3log2(64)=?
2log5(25)-3log2(64)=?
log的计算 :log2(20)-log4(25)= log3(2)×log2(5)×log5(3)=?log2[log
log2^25*log3^2倍根号2*log5^9=
我是这样做的log2(3)*log3(5)*log5(49)*log7(64)=log2(3)*log3(5)*2log
(log3^4+log5^2)(log2^9+log2^根号3)
有关log的数学题①log2(2X+3)=0②log5(X)-1/3log5(8)=0③log2(X)+log4(X)=
log2(2)+log5(1)-log1/3(1/27)+[3^log3(5)]^2+3^-log3(2)=?
求值 3^2-log3(2)= log7(log5(log2(32)))=?
求x的值 log4^x=-2/3 log2^(log5^x)=0
log2/27及 log 3=a log5=b
log2^5*log3^2倍根号2*log5^9=
log2 25*log3 4 *log5 9
