Which function dominates x^p or p^x

Mathematics

maxonik [38]3 years ago

I'm assuming p\in\mathbb R is fixed. First note that x^p=p^x when x=p.

We can rewrite each expression as

x^p=e^{p\ln x}
p^x=e^{x\ln p}

Now to compare we only need to consider the exponents. It's easy to show that x>\ln x for all x>0, so it follows that x^p so long as x>p.

How to get x by it's self 12 - 12x = -6x + 48
anastassius [24]

Answer:

Step-by-step explanation:

12 - 12x = -6x + 48

Add 12x to both sides. That eliminates the x term on the left side.

12 = 6x + 48

Subtract 48 from both sides. That eliminates the constant term on the right side.

-36 = 6x

x = -6
