2log2 10—log2 25=?

2log2 10—log2 25=? lg(1/4)-lg2(5) 2log5(10)+log5(0.25) 2log2(25)-3log2(64) log2(log2(16) ) (log2 9)/(log2 8) = 2/3(log2 3) log2 (log2 16)=? log的计算 ：log2（20）-log4（25)= log3(2)×log2（5）×log5（3）=?log2[log2(32)-log2(3÷4）+log2log的计算 ：log2（20）-log4（25)= log3(2)×log2（5）×log5（3）=?log2【log2(32)-log2(3÷4）+log2（6）】=?lgx+lg（x+15）=2 ..X 2log2^3= 2^log2(20)=? log2(x – 2 ) + 2 = log2(5)log2(x – 2 ) + 2 = log2(5) log2(x – 2 ) + 2 = log2(5)log2(x – 2 ) + 2 = log2(5) log2 (x + 3) + log2(x + 2) = 1log2 (x + 3) + log2(x + 2) = 1 (log2) ^2 - log5 *log20课本上 等于 （log2）^2 +(1+log2)(1-log2) = 1;（log2）^2 +(1+log2)(1-log2) 是怎么来的? log2 4+log2 (x+2)怎么算?log2 4+log2 (x+2)=log2 (4x+8) 若log2 36=a,log2 10=b,则log2 15等于多少2是底数快 2log5 10+log5 0.25= 2log5 25-3log2 64= log2(log2 16)= 已知lg2=a,lg3=b,求log3 4,log2 12 在等比数列｛an｝中,公比q=2,且log2 a1+log2 a2 +log2 a3+……+log2 a10=25 求a1+a2+.a10= log2^(x^log2^x)=? log2 27/log2 9= [log2 1]+[log2 2]+[log2 3]+[log2 4]+[log2 5]+...+[log2 1024]=?[x]表示不超过x的最大整数2为底 答案是8204
