问：(1/4)-(-5)*(-1/3)-(-1/4)+(-52/(

答：亲您好很高兴为您解答，(1/4)-(-5)*(-1/3)-(-1/4)+(-52/(是(1)4﹣5×(﹣)﹣|﹣5|(2)﹣12016+0.5÷(﹣)5×[2﹣(﹣5)]。计算：(1)4﹣3×(﹣ )﹣|﹣5|(2)﹣1 2016 +0.5÷(﹣ )3 ×[2﹣(﹣3)]．题目来源： 江苏省扬州市江都区花荡中学2015-2016学年度七年级数学上学。

答：亲，计算题N道1.(-1/4)^5*(1/4)^3*(-1/4)^22.(b^2)^3*(b^3)^4/1.(-1/4)^5*(1/4)^3*(-1/4)^2 =(-1/4)^(5+2)*(1/4)^3 =(-1/4)^7*(1/4)^3 =-(1/4)^7*(1/4)^3 =-(1/4)^(7+3) =-(1/4)^10 =-[(1/2)^2]^10 =-1/2^20 2。
