log2 20-log4 25

log2 20-log4 25 log2 20-log4 25的答案是 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 log2 20---log2 5+log3 4 * log4 3 等于什么 log2(20)-log2(5)+2log3(2)×log4(3) log的计算log2为底 20-log4为底 25 log2 20-log4 25=?我要步奏.我是个S,B要最详细的 log4(log2^x)=log2(log4^x)求log2^x log4^25-2log4^10+log2^9×log3^根号5×log5^2 log2^x=log4^9 2log2为什么等于log4 [log2 (125) +log4(25)+log8(5)][log125(8)+log25(4)+log5(2)][log2 (125) +log4(25)+log8(5)][log125(8)+log25(4)+log5(2) log4 243 - log8 729=?log4 12 - log2 6=? 3^log9(25)+16^log4(2)-(根号7)^log7(9)+(-1)^log2(1) 求值：3^(log3 (25) )+(-C(5,4)^(log2 1)+16^(log4(2sin(π/2))= [log2 (125) +log4(25)+log8(5)][log125(8)+log25(4)+log5(2) log2(X+1)+log0.25(X-1)>log4(2X-1)的解为多少? log4 25怎么化成log2 回答都很好，不过一楼是匿名，
