(-0.25)四次方×(-8)三次方+[(-三又 1/3)二次方-4/13×(-6.5)+(-2)四次方÷﹙﹣6﹚]÷﹙﹣三的二次方分之一﹚
=-0.25×（0.25×8)三次方+[100/9+2+16÷﹙﹣6﹚]÷﹙﹣1/9﹚
=-0.25+[100/9+2-8/3]×(-9)
=-0.25-100/9×9-2×9+8/3×9
=-0.25-100-18+24
=-118.25+24
=-94.25请问(-0.25)四次方×(-8)三次方是怎么变成0.25×（0.25×8)三次方而且100/9+2+16不应该是 100/9－2+16而且0.25×（0.25×8)三次方不是等于2吗(-0.25)四次方×(-8)三次方=-0.25×(0.25)三次方×(8)三次方=-0.25×（0.25×8)三次方=-0.25(-三又 1/3)二次方=100/9-4/13×(-6.5)=2(-2)四次方÷﹙﹣6﹚=16÷（-6）怎么不是？？？？
