GP中,{an}中,an>0.a4*a5=32求log2a1+log2a2+…+log2a8GP中,{an}中,an>0.a4*a5=32求log2a1+log2a2+…+log2a8GP中,{an}

GP中,{an}中,an>0.a4*a5=32 求log2a1+log2a2+…+log2a8
GP中,{an}中,an>0.a4*a5=32 求log2a1+log2a2+…+log2a8

GP中,{an}中,an>0.a4*a5=32 求log2a1+log2a2+…+log2a8
log2a1+log2a2+…+log2a8=log2(a1*a2*...*a8)=log2((a4*a5)4)=4*log2(32)
=20
