解：
log2(√6)-log2(9^#8531;)
=#189;log2(6) - #8531;log2(9)
=#189;[log2(2)+log2(3)] - #8531;×2×log2(3)
=#189;log2(3)+#189; - #8532;log2(3)
=log2(√2)+(#189;-#8532;)log2(3)
=log2(√2)-(1/6)log2(3)
=(1/6)log2(8) -(1/6)log2(3)
=(1/6)[log2(8)-log2(3)]
=(1/6)log2(8/3)
8/3;0，(1/6)log2(8/3);0
log2(√6)-log2(9^#8531;);0
log2(√6);log2(9^#8531;)
log2(√6)-log2(9^#8531;)
=#189;log2(6) - #8531;log2(9)
=#189;[log2(2)+log2(3)] - #8531;×2×log2(3)
=#189;log2(3)+#189; - #8532;log2(3)
=log2(√2)+(#189;-#8532;)log2(3)
=log2(√2)-(1/6)log2(3)
=(1/6)log2(8) -(1/6)log2(3)
=(1/6)[log2(8)-log2(3)]
=(1/6)log2(8/3)
8/3;0，(1/6)log2(8/3);0
log2(√6)-log2(9^#8531;);0
log2(√6);log2(9^#8531;)
