Having a hard time figuring out what is being asked here

It mentions how to use JavaScript exponents at the end of the task, but I don't understand what I need to use it for or how to adjust the calculations given to be JavaScript friendly...

Circle.js 
class Circle {
    set radius(radius){
      const pi = 3.14
      this._radius = radius;
      this.circumference = 2 * pi * radius;
      this.area = pi * radius ^ 2;
    }

}

const circ = new Circle();

The symbol "^" doesn't represent an exponent operation in JavaScript like it does in math. But if you follow the link, it takes you to documentation for the "Math.pow" function that will do the job.

And another way to square something is to just multiply it by itself:

      this.area = pi * radius * radius;

Thanks! I was super confused. Thought I was being asked to use the ^ symbol there
