You square the number in the parentheses.
Yes, and parenthesis are the first thing you solve.
You multiply the outside number touching the parenthesis by the numbers inside. Ex: 6(x - 5) = 42 6x - 30 = 42 6x = 72 x = 12

You expand the parenthesis out first. Then simplify the rest.
Parentheses is when you are doing an equation, and you solve the problem.

it means that you have to solve the exponents first and then do the rest. it follows a rule called PEMDAS:ParenthesisExponentMultiplicationDivisionAdditionSubtraction
When it is convenient
x
sin(arcsin(2/3)) = 2/3, since sin is the inverse function of arcsin.
