log2 24-1/log3 2=
log2(3)+log3(5)+log3(2)=?
log2(2)+log5(1)-log1/3(1/27)+[3^log3(5)]^2+3^-log3(2)=?
log2(3)=a,log3(7)=b.log12(56)=log3(7*8)=log3(7)+3log3(2)
log2 3×log3 7=log2 7
若a=log2 3.b=log3 2,c=log1/3 2.d=log2 1/3
log2(3)*log3(4)*log4(5)*.log(k+1)(k+2)=log2(k+2) 怎么证
log3 7·log2 9·log49 a=log4 1/2,则a=
1.9^log3(2)-2^[1+1/2log2(5)]
log2 4=2log3 9=3
log2^25*log3^2倍根号2*log5^9=
log2^5*log3^2倍根号2*log5^9=
已知log3^2=a则log2^9等于多少
