c) \( 5 x^{0} \)

Did you know that any non-zero number raised to the power of zero equals one? So, in the case of \( 5x^{0} \), you can simplify it to just \( 5 \). It's a nifty little rule that saves time and confusion! In real-world applications, you might encounter this concept frequently in fields like economics or physics, where constants come up regularly in equations. For instance, if you're calculating costs or forces that don't change, you'll often find terms like \( 5 \) instead of fussing with variables that might not even matter at that moment!
