2log5(25)-3log2(64)
2log5(25)-3log2(64)=?
(log3^4+log5^2)(log2^9+log2^根号3)
log的计算 :log2(20)-log4(25)= log3(2)×log2(5)×log5(3)=?log2[log
我是这样做的log2(3)*log3(5)*log5(49)*log7(64)=log2(3)*log3(5)*2log
log2^25*log3^2倍根号2*log5^9=
log2 25*log3 4 *log5 9
利用换底公式求值:1.log2 25 ×log3 4 ×log5 9 2.(log4 3+log8 3)(log3 2+
