在整式的运算学习中,关于单项式次数规定单独一个非零数的次数是0,同底数幂的除法中规定“a0=1(a≠0)”。同学们在短时间内清楚区分两者含义有一定的难度,例如多项式8x2y+3x-9中第三项“-9”的次数是0次;而在代数式(-9)0=1中-9的次方也是0,同学们难以分辨、容易混淆。笔者通过 In integer arithmetic learning, the number of times that a single nonzero number is specified for a monomimetic number is 0, and the division with the power of the base specifies “a0=1(a ≠ 0)”. It is difficult for the students to clearly distinguish between the two meanings within a short period of time. For example, the number of the third “-9” in the polynomial 8x2y+3x-9 is 0; and in the algebraic equation (-9) 0=1, the-9 The power of the party is also 0. The students are difficult to distinguish and easy to confuse. The author passed
