all right. Hey, guys. So in this problem, we were given the squared of 625 were asked to find out what square to 625 equals to basically, simple by the expression. So when we have square to 6 25 when we're taking a square root in this case, just wanna recap that we're taking the principal square and principal square root basically means the positive square. And I'm just gonna explain that really quickly again. What it means explain a little bit in the last video, we'll just to recap. So when you have the squirt of six, when you have 6 25 you know that 6 25 is a perfect square. It's equal to 25 squared, and it's also equivalent to negative 25 square. So when you have the square root of 6 25 this is equal to the plus or minus the positive or negative value of 25. But since you're taking the principal square root, you're on Lee concerning yourself, with the pause that value. And that means that square root of 6 25 as expressed in this problem, is just equal to pause to 25. And this is the answer to this problem
