The following calculation results are correct () A. （ab）3÷ab=ab2B. 1010÷1010=0C. （x+y）6÷（x+y）3•（x+y）=（x+y）2D. （a-2b）3÷（-a+2b）3=-1

A. (AB) 3 ／ AB = a2b2, so this option is wrong; B, 1010 ／ 1010 = 1, so this option is wrong; C, (x + y) 6 ／ (x + y) 3 · (x + y) = (x + y) 4, so this option is wrong; D, (a-2b) 3 ／ (- A + 2b) 3 = - 1, so this option is correct; so D
