Math help (algebra 1&2 rules)?

What are the steps, solution (explanation) and answer to simplifying the following problems

1.) (4 + a^{2} - b + c^{3} / (10 - a^{3} + b^{-3}))^{-3}

2.) (2.14 + a^{2} - b + c^{3} / (24.2 - a^{3} + b^{-3}))^{2}

3.) (2.14 • a^{2} • b • c^{3} / (24.2 • a^{3} • b^{-3})^{2}

4) (2 • a^{2} • -2b^{-3} • c^{3} / (24 • a^{3} • b^{3} • 3c^{3}))^{-2 }

Sorry, I'm having a difficult time learning the rules surrounding these questions and I have a big test tomorrow to be eligible for a university, thank you !

The steps:

1) Attempt the problems yourself.

2) Show your working out and exactly where you are stuck.

The solution will appear when you are given some guidance on overcoming where you are stuck and when you complete the problems.

The final answer will appear once you have verified that all your working out is correct.
