计算：log2(log2 32-log2 3/4+log2 6)

log2 3/log2 5等于log2 3-log2 5么? log2 5/4+log2 5 log2 3乘以log2 3等于2log2 (log2 9)/(log2 8) = 2/3(log2 3) (log3^4+log5^2)(log2^9+log2^根号3) log2 3×log3 7=log2 7 计算log2 6-log2 3,lg5+lg2,log5 3+log5 1/3,log3 5-log3 15 4^log2 3等于多少? 根号下[(log2^3)^2-4log2^3+4]+log2^(1/3) 解方程log2(x+14)-log2(x+6)=3-log2(x+2) log2(6)等于多少 log2(6)等于几
