Let m be an odd integer. Show m^(2n) ≡1 mod 2^(n+2) for all positive natural numbers n.

So, I'm pretty sure that m^(2n) is odd, while 2^(n+2) is even. But then I'm not sure how to go about showing this...

People are looking for a similar civilisation in outer space hoping to share information and make friends. Do they look for a twin civilisation just like ours here on Earth? So they need to find a planet with just the right water and air temperatures (~55-75 degree F range) et cet. But what is civilisation? Ants and bees live in colonies. Are they what we need? No. We think about civilisations that do have computers and flying machinery. But we people have this equipment because we do not have wings and powerful enough brains so we need these technological crutches.

It's possible that some civilisations can move around using power of their will, so they do not need clumsy machinery at all. Imagine life made from waves, or size of 5 million galaxies, or invisible carbon-fluoride slime that can create and destroy whole universes. And these entities will reproduce asexually. How do we contact and make friends with them? Is our search for civilisations the same as that for gods (God)?

Just incase you didnt understand, ^ means that it is to the power of, so 2^(x+4) means 2 to the power of x+4. Any help would be appreciated.

Two point charges are placed on the x-axis as follows: one positive charge, q_1 = 4.01 nC, is located to the right of the origin at x= 0.202 m, and a second positive charge, q_2 = 4.98 nC, is located to the left of the origin at x= -0.296 m.

What is the total force (magnitude and direction) exerted by these two charges on a negative point charge, q_3 = -5.98 nC, that is placed at the origin?

I think you are supposed to use couloumbs law to calculate the answer. I got 8.35 x 10^-6 C but its wrong for some reason. Please help
