(log2 9)/(log2 8) = 2/3(log2 3)
(log2 9)/(log2 8) = 2/3(log2 3)
log(2,9)=log(2,3^2)=2log(2,3)
log(2,8)=log(2,2^3)=3log(2,2)=3
所以(log2,9)/(log2,8) = 2/3(log2,3)
(log2 9)/(log2 8) = 2/3(log2 3) 2^(log2^(-3))= log2 3乘以log2 3等于2log2 log2 3×log3 7=log2 7 log2 3/log2 5等于log2 3-log2 5么? 2^log2 (3) × log2 (1/8) + 2lg3 (log3^4+log5^2)(log2^9+log2^根号3) log2 (x + 3) + log2(x + 2) = 1 (log8 9/log2 3)=? LOG2^3=A,LOG2^5=b,则log2^9/5值是多少 解方程log2(x+14)-log2(x+6)=3-log2(x+2) log8(9)*log2(3)
