Um... Do you perhaps mean "simplify these two"...? (If not, then I'm afraid I don't understand your post...?)

For the first expression, you need to simplify from the inside out, using the order of operations. Since you didn't show any work, I don't know where you're having trouble, but the following sequence of lessons should suffice to enable you to begin:
. . . . .Negative Numbers. . . . .The Order of Operations. . . . .Simplifying with ParenthesesFor the econd expression, your formatting is a bit unclear, but I'm fairly certain you are being asked to use exponent rules to simplify the expression. If so, then the following should be sufficient to get you going:
. . . . .Exponents. . . . .Simplifying with ExponentsOnce you have studied the lessons and learned the basic terms and techniques, please attempt the exercises. If you get stuck, you will then be able to reply with a clear listing of your steps and reasoning so far.
Thank you!
