|log3(5)-2|+log9(25)+(1/32)^1/5
log3 5-log3 15+1/2log9 27 的值
由换底公式怎么得到log9(x+5)=log3[2(x+5)]=1/2log3(x+5)
(log4 3+log8 3)(log3 2+log9 2)-log1/2 32^1/3+5^(log25 9)
计算(log4 3+ log8 3)(log3 2+ log9 2)-- log1/2 32^(1/3)+5^(log2
(1)log4 27乘以log25 8乘以log9 5 (2)(log4 3+log8 3)(log3 2+log9 2
log 243÷log9 =log3^5÷log3^2 =log3^5-log3^2 然后怎么写
-5log9为底4的对数+log3为底(32/9)的对数-5^(log5为底3的对数)-(1/64)^(-2/3)
填空题:方程log3(x-1)=log9(x+5)的解是____________
log3(5)+log9(5)求大神帮助
