Math - How to solve Radical Expressions

Even though radicals are for high school people and whatnot, I find that learning about radicals can help you alot. Radicals aren't hard tough the concept can be very confusing. Radicals are very similar to exponents because problems like, the square root of 36 is equivalent to 6 because 6 twice is 36. All those numbers that can be times itself, not to be confused by the doubling by adding, it is doubling by multiplying, are called perfect squares. The square root symbol is similarly to the long division symbol except that at the end there is a hook which is what makes the square root symbol different from the division symbol.
