充颜颖15648853810 ______ (log32+log92)?(log43+log83)=(log32+1 2 log32)?(1 2 log23+1 3 log23)=log323 2 ?log235 6 =3 2 *5 6 =5 4 故答案为:5 4

强峰鬼1084(log2 3+log4 9+log8 27+...+log2^n 3^n)log9 32的N次方根 -
充颜颖15648853810 ______ log4 9=2lg3/2lg2 =lg3/lg2=log2 3 log2 3+log4 9+log8 27+...+log2^n 3^n=nlog2 3=nlg3/lg2 log9 32的N次方根(log2 3+log4 9+log8 27+...+log2^n 3^n)log9 32的N次方根=(1/n)(5lg2/2lg3)*nlg3/lg2=5/2

强峰鬼10842log5 10+log5 0.25等于多少 -
充颜颖15648853810 ______ 2log5^10+log5^0.25=2lg10/lg5+lg0.25/lg5=lg100/lg5+lg0.25/lg5=(lg100+lg0.25)/lg5=lg25/lg5=2lg5/lg5=2希望对您有所帮助如有问题,可以追问.谢谢您的采

强峰鬼1084已知3^a=5^b=A,若1/a+1/b=2,则A= 已知log8(9)=a,log2(5)=b,则lg3= -
充颜颖15648853810 ______ 1. 已知3^a=5^b=A,那么:log3 (A)=a,log5 (A)=b即有:logA (3)=1/a,logA (5)=1/b若1/a+1/b=2,那么:logA (3) + logA (5...
