Eli5: How operations with roots work.

504 viewsMathematicsOther

I’m about to take a college entrance exam and I just can’t make sense of it all. A friend of mine called them “spicy fractions” but I genuinely do not understand. Like, what does it mean, in a physical and earthly sense when you have something like 5[Square root of 2] (which according to this, it’s 50). What is this notation for, and what does it accomplish in a real world setting? What properties apply to them, and how do you even *get* to these types of numbers?

Your example is incorrect, we might be able to help better if you find the actual problem your having troubles with. 

Edit: do you mean 5 SQUARED, times 2?
