write a program the computes nx and store the result into y You can use y = Math.pow( Mantissa, exponent)Requirements:Besides main() your program must have one method with two parameters, one double and one int n and x are positive numbers read from the keyboardif the user makes an entry that does not meet this criterion, the user must be given to opportunity retry the entry the user must be able to quit prior to entering values for n and x Your method must compute y and return the result to its caller; the caller will print the result After printing the result, the user must be queried again if there are other values to compute; if the answer is no exit the program, but if the user replies yes, then repeat the computation

Einstein is a bright mathematician. Today he is investigating whether an integer is divisible by some square number or not. He has a positive integer I represented as a product of N integers a1, a2, .... aN. He has somehow figured out that there exists some integer P such that the number I is divisible by P2, but he is not able to find such P himself. Help him develop a code in python that prints the possible value of P possible, you can print any one of them.Sample Input:1321 11 6Output:3
