log2^25*log3^2倍根号2*log5^9=
log2^5*log3^2倍根号2*log5^9=
(log3^4+log5^2)(log2^9+log2^根号3)
log4^25-2log4^10+log2^9×log3^根号5×log5^2
高中对数log2(9)*log3(根号5)*log5(2)
log2 25*log3 4 *log5 9
log的计算 :log2(20)-log4(25)= log3(2)×log2(5)×log5(3)=?log2[log
利用换底公式求值:1.log2 25 ×log3 4 ×log5 9 2.(log4 3+log8 3)(log3 2+
log2(2)+log5(1)-log1/3(1/27)+[3^log3(5)]^2+3^-log3(2)=?
我是这样做的log2(3)*log3(5)*log5(49)*log7(64)=log2(3)*log3(5)*2log
(log3 4+log3 8)(log2 3+log2 9)+(log3 根号2)(log9 7)/(log1/3 7)
