人教版八年级上册数学教材第十四章第一节前面讲了三种幂运算,其顺序和名称依次是同底数幂的乘法、幂的乘方、积的乘方,笔者认为应将积的乘方更名为同指数幂的乘法,并将其提到第二的位置,即依次为:同底数幂的乘法、同指数幂的乘法、幂的乘方.其理由如下:首先,积的乘方即(ab)~n=a~nb~n(n为正整数),从左到右为积的乘方运算,但从右到左实质就是同指数
PEP Teaching and learning materials eighth grade mathematics textbook Chapter fourteenth first section I spoke in front of the three kinds of exponentiation, followed by the same order and name of the same power multiplication, exponentiation, product of the power, I believe that should be plot The power is renamed to multiply the same exponential power, and referred to the second position, namely: the same power multiplication at the end of the same exponential power multiplication, exponentiation for the following reasons: First, the product of The power of (ab) ~ n = a ~ nb ~ n (n is a positive integer), from left to right for the product of the power operation, but from right to left is essentially the same index
