were asked to solve the equation. B squared equals 100. Since we're dealing with a perfect square, which you think of writing wasn't 100 as a perfect square and 100 is the same thing as 10 squared. Now that we have perfect squares on both sides of the equation, Weaken square. Root both sides of the equations to get rid of the squares. So if we square root both sides, the square root in the square counteract on each side, leaving us with B equals 10. I don't forget the square root property when you square root. A positive number is the positive and negative value of that number. So I get to write this in set notation. We have two solutions here. If B squared equals 100 B could be either negative 10 or he could be a little 10 negative or positive. 10
