计算:(1)log2 (4^3*8^5);(2)log2 3+log2 6-log2 9
(log2 9)/(log2 8) = 2/3(log2 3)
log2 3/log2 5等于log2 3-log2 5么?
计算log2.5(6.25)+lg1/100+In根号下e+2[1+log2(3)]
(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
2^log2 (3) × log2 (1/8) + 2lg3
根号下[(log2^3)^2-4log2^3+4]+log2^(1/3)
log2(√1/48)+log2 12-1/2log2 (24)-1/3
log2 3乘以log2 3等于2log2
计算log2 6-log2 3,lg5+lg2,log5 3+log5 1/3,log3 5-log3 15
log2 5/4+log2 5
(log3 4+log3 8)(log2 3+log2 9)+(log3 根号2)(log9 7)/(log1/3 7)
