问题描述
在phython我知道找到一个完美立方体的立方根，但我怎么能找到一个数字的立方根，如9,7,17 ...这不是一个完美的立方体我想要大致的回答如下：
例如：
输入：num = 9
输出：2.08
我尝试过：
in phython i know find a cube root of perfect cube but how i can find a cube root of number like 9,7,17...which are not a perfect cube i want approx answer like:
example:
input:num=9
output:2.08
What I have tried:
cube=int(input(' enter a vlue to find it cube root,(vlue must be >1):'))
epsilon=0.01
num_guess=0
low=0
high=cube
guess=(high+low)/2.0
while abs(guess**3-cube)>=epsilon:
if guess**3<cube:
low=guess
else: #guess**3>=guess
high=guess
guess=(high+low)/2.0
num_guess+1
print('number of guess=',num_guess)
print(guess)推荐答案
n=int(input('enter a value of which root you want to find(ex.for squreroot type 2,cuberoot type 3):'))
d=int(input('enter a no. to find root of it:'))
x=1/n
print('your ans.=',d**x)
#now its look like pythonikkkkk.....
