Pow (Swift)

var a = 2, b = 3 //(a+4b)(a–3b)+a^2 var res = (a + (4 * b)) * (a - (3 * b)) + pow(Double(a),2) print(res) //I do not know how to square, for some reason the answer is not displayed

This one import Foundation var a = 2, b = 3 //(a+4b)(a–3b)+a^2 var res = (a + 4 * b) * (a - 3 * b) + Int(pow(Double(a),2)) print(res) Becomes - 94 Don't know if you need a Integer Result, or a Double Result

Try: import Foundation I've tested this, and it's running import Foundation var res = pow(5.0,2) print(res) https://stackoverflow.com/questions/24012511/mathematical-functions-in-swift

But this is also working: import Foundation var a = 5 var res = pow(Double(a), 2) print(res)

Yes it works, but for some reason it doesn't work for me in the equation (
