My ah-ha moment this week was when we had to form radicals into entire radicals, or the other way around to mixed radicals.
Before that was the question that I really struggled with because it was difficult to know all the perfect squares or perfect cubes. But once i memorized them and knew how to deal with them it was less confusing and it was way easier for me to solve those questions.
In the picture you can see the question that helped me understand the topic. We had to change the mixed radicals into entire radicals. Once I figured out how to do that I did´t have an trouble doing the other questions of that type. Solving the terms in the picture even helped me for the test, because there we also had to simplify or rearrange terms.
