若{an}(an>0)成等比数列,a1a100=64,求log2a1+log2a2+…+log2a100

若{an}(an>0)成等比数列,a1a100=64,求log2a1+log2a2+…+log2a100
若{an}(an>0)成等比数列,a1a100=64,求log2a1+log2a2+…+log2a100

若{an}(an>0)成等比数列,a1a100=64,求log2a1+log2a2+…+log2a100
log2a1+log2a2+…+log2a100
=log2(a1*a2*...a100)
=log2(a1*a100)^50
=50log2(64)
=50x6
=300
