[-0.5²+﹙-1/2﹚²－|-2²-4|+﹙2 又1/4﹚²×26/27]÷﹙0.1﹚²
[-0.5²+﹙-1/2﹚²－|-2²-4|+﹙2 又1/4﹚²×26/27]÷﹙0.1﹚²
[-0.5²+﹙-1/2﹚²－|-2²-4|+﹙2 又1/4﹚²×26/27]÷﹙0.1﹚²
[-0.5²+﹙-1/2﹚²－|-2²-4|+﹙2 又1/4﹚²×6/27]÷﹙0.1﹚²
=[-0.25+1/4-|-4-4|+9/4×6/27]÷0.01
=(-0.25+0.25-8+0.5)÷0.01
=(-7.5)÷0.01
=-750
我认为你的题目这里（26/27）应该是（6/27）,所以我按 （6/27）算的.
结果是-625/2
