What are those mysterious square roots that often confuse students and complicate their lives? The truth is that to understand them, we need to grasp the concept of the inverse operation. What do we mean by this? When we solve an exercise like "How much is 5 squared?" it's clear that 5 multiplied by 5 gives us a result of 25. This is the concept of powers or, to be more precise, squaring a number. To apply it, we multiply the figure or number by itself. But what happens when we encounter an exercise where X squared equals 25? In this case, we must perform an inverse operation, and this is when square roots come into play.
