|log3(5)-2|+log9(25)+(1/32)^1/5

|log3(5)-2|+log9(25)+(1/32)^1/5 log3*2/log9*4 log3 5-log3 15+1/2log9 27 的值 log3*2/log9*4=? log 243÷log9 =log3^5÷log3^2 =log3^5-log3^2 然后怎么写 已知log3(4)=a,log3(5)=b 则log9(16/25)= 已知log3(4)=a,log3(5)=b 则log9(16/25)= 化简:log2 2+log5 1-3^(2log9 5)+(3log3 5)^2+3^log3 2 log2^1/25×log3^8÷log9^5+(-1/2)^-2×(In兀)^0÷8^2/3 log9^3+log2^1/25×log3^1/8×5^1/9= (log4 3+log8 3)(log3 5+log9 5)(log5 2+log25 2)= -5log9 4+log3 32/9-5^log5 3-(1/64)^-2/3 计算：-5log9^4+log3^32/9-5log5^3-(1/64)^-2/3 (log2^3 +log3^5) x ( log3^5 +log9^5 ) x lg 2 ,本人对数特别差,最好带解说,(log2^3 +log5^3) x ( log3^5 +log9^5 ) x lg 2 计算[log9(5)+log3(5)]乘[log25(3)+log125(9)] 为什么log9(2)=log3(2)/2如题 方程log3 (x-1)=log9 (x+5) 解方程log3^(x-1)=log9^(x+5)
