Akar pangkat tiga dalam matematika python

Jika kita ingin mencari akar pangkat tiga dari bilangan bulat negatif. Kemudian kita harus melakukan beberapa perubahan pada trik di atas

a=-125
print(-(-a)**(1/3))

-5.0

Berfungsi untuk mencari akar pangkat tiga menggunakan Python

Kita dapat mendefinisikan fungsi untuk akar pangkat tiga. Ketika pengguna memasukkan angka untuk akar pangkat tiga, maka secara otomatis akan mengembalikan akar pangkat tiga dari angka tersebut

def cube_root(x):
        return x**(1/3)
print(cube_root(27))

Seperti yang bisa kita lihat, saya telah mendefinisikan fungsi akar pangkat tiga. Dan saya telah memanggil fungsi yang sama dengan input 27. Jadi itu akan mengembalikan akar pangkat tiga dari 27

Jika suatu bilangan dikalikan dengan dirinya sendiri dua kali (n*n*n), bilangan terakhirnya adalah pangkat tiga dari bilangan tersebut dan mencari akar pangkat tiga dari suatu bilangan adalah operasi kebalikan dari pangkat tiga bilangan tersebut. Jika x adalah akar pangkat tiga dari y, dapat dinyatakan seperti di bawah ini

Atau, itu juga dapat dinyatakan sebagai

x3 = y

Metode 1. Menggunakan operator eksponensial (**).

Eksponensial (**) operator Python dapat digunakan untuk menghitung akar pangkat tiga dari sebuah angka. Perhatikan contoh berikut
