题目：给定一个double类型的浮点数base和int类型的整数exponent。求base的exponent次方
思路：引入math库即可
java代码：
ublic class Solution { public double Power(double base, int exponent) { return Math.pow(base,exponent); } }
python代码：
# -*- coding:utf-8 -*- import math class Solution: def Power(self, base, exponent): return math.pow(base,exponent)
