6,951 PointsWhy is my solution not accepted? This regards: Protocol extensions Challenge 1 of 1. I import Foundation and use sqrt
// Enter your code below import Foundation extension Calculator { func square(_ value: Double) -> Double { return sqrt(value) } }
protocol Calculator {
func square(_ value: Double) -> Double
}
// Enter your code below
import Foundation
extension Calculator {
func square(_ value: Double) -> Double {
return sqrt(value)
}
}

5,602 PointsAll of it looks spot on except for the last line.
Instead of returning "sqrt(value)", you need to return "value * value". Remember that you're squaring the value, not finding the square root of it.
Hope that helps!
