5^21乘以4^11除以2的详细解答和答案

5^21x4^11/2可以化简为5^21x2^22.5，因为4^11/2=2^11。

然后可以进一步化简，将5^21和2^22.5分别写成素因子分解的形式：

5^21 = 5x5x5x5x5x5x5x5x5x5x5x5x5x5x5x5x5x5x5x5x5x5

2^22.5 = 2x2x2x2x2x2x2x2x2x2x2x2x2x2x2x2x2x2x2x2x2x2x2x2x√2

然后将它们相乘，得到：

5^21x2^22.5 = 5x5x5x5x5x5x5x5x5x5x5x5x5x5x5x5x5x5x5x5x5x5x2x2x2x2x2x2x2x2x2x2x2x2x2x2x2x2x2x2x2x2x2x2x2x2x2x2x√2

这就是最简形式的答案。
