Python: Square Root Simplification

 Python: Square Root Simplification



Introduction


The script SQFACTOR.py attempts to factor and simplify square root expressions in the form of either:


1.  √n

2.  √m + √n


The script was created using the TI-83 Plus Premium CE Python Edition, which is my first Python script using the French calculator.  




Python script:  sqfactor.py


from math import *

# basic code


def sqfactor(n):

  c=1

  k=2

  while k**2<n:

    while (n/k**2)-int(n/k**2)==0:

      n/=k**2

      c*=k

    k+=1

  return [c,n]


# 2 forms

print("Select: ")

print("1. sqrt(n)")

print("2. sqrt(m)+sqrt(n)")

ch=int(input())


if ch==1:

  n=float(input("n? "))

  l=sqfactor(n)

  print("sqrt("+str(n)+")=")

  print(str(l[0])+"*sqrt("+str(l[1])+")")


if ch==2:

  m=float(input("m? "))

  n=float(input("n? "))

  l0=sqfactor(m)

  l1=sqfactor(n)

  c=l0[0]

  d=l0[1]

  r=l1[0]

  s=l1[1]

  print("sqrt("+str(m)+") + sqrt("+str(n)+")")

  if d==s:

    print(str(c+r)+"*sqrt("+str(d)+")")

  else:

    print(str(c)+"*sqrt("+str(d)+")+")

    print(str(r)+"*sqrt("+str(s)+")")



Examples



Example 1:


√1640

Result:  2 * sqrt(410.0)


Example 2:


√56 + √78

Result:  2 * sqrt(14.0) + 1 * sqrt(78.0)


Example 3:


√75 + √27

Result:  8 * sqrt(3.0)
