(log3 2+log9 2)*(log4 3+log8 3)求值
(log3 2+log9 2)*(log4 3+log8 3)求值
(log3 2+log9 2)*(log4 3+log8 3)求值
(log3 2+log9 2)*(log4 3+log8 3)
=(lg2/lg3+lg2/lg9)*(lg3/lg4+lg3/lg8)
=(lg2/lg3+lg2/2lg3)*(lg3/2lg2+lg3/3lg2
=3/2*lg2/lg3*5/6*lg3/lg2
=3/2*5/6=5/4
log3 2 等于 lg2\lg3 这样化开算！！！
结果5\4 1.25
(log3 2+log3 根号2)*(log2 根号3+log2 三次根号3)
=(log3 2根号2)*[log2 (根号3)(三次根号3)]
=[(3/2)(log3 2)]*[(5/6)(log2 3)]
=5/4
log3*2/log9*4
log 243÷log9 =log3^5÷log3^2 =log3^5-log3^2 然后怎么写
log3*2/log9*4=?
(log3 4+log3 8)(log2 3+log2 9)+(log3 根号2)(log9 7)/(log1/3 7)(log三次根号4 8)
log3 5-log3 15+1/2log9 27 的值
对数不同底数相乘如何运算,(log以4为底3+log以8为底3)*(log3为底2+log9为底2)求教~
化简log2[log3(log5 125)]……1.化简log2[log3(log5 125)]2.5log2(log9 81)3.log9 4 +log3 8 /log1/3 164.求值(lg2)^2+两个2*lg5+lg503.log9 4 +log3 8除以log三分之一 16 4.求值(lg2)平方+lg2乘以lg5+lg50
为什么log9(2)=log3(2)/2如题
(log3 2+log9 2)*(log4 3+log8 3)求值
化简(log4(3)+log8(3))(log3(2)+log9(2))
(log3^2 + log9^4)×(log4^3 + log8^3)
|log3(5)-2|+log9(25)+(1/32)^1/5
计算log9底8分之log3底2
为什么log9 (9/2)=log3(81/4)
求值:(log4^ 3+log8 ^9)*(log3^ 2+log9 ^16)
化简:log2 2+log5 1-3^(2log9 5)+(3log3 5)^2+3^log3 2
(log2(3)+log8(9))x(log3(4)+log9(8)+log3(2))
求（log2^3+log8^9)(log3^4+log9^8+log3^2)的值
