This all depends on the content you are studying, and what learning style works for you. One thing that works for most people is repetition. Although it sucks, it works because that’s how our brains are wired. Tell yourself, “I will not stop studying until I understand this concept or calculation,” for example. Then take a break once you are comfortable with it. Repeat again as needed. Start studying early and only study what you don't know. Try to be as consistent as possible. Good luck!

Answer:

83.6155156

Step-by-step explanation:

$\frac{ {16}^{2} - 17 }{ \sqrt{2.3 + 5.87} } \\ \\ = \frac{ 256 - 17 }{ \sqrt{8.17} } \\ \\ = \frac{ 239}{2.85832119 } \\ \\ = 83.6155156 \\$
