Mr.Owl

The only way for protons in the nucleus to leave an atom is if the element changes to a new element.

So if you have a chemical reaction and you can change what element an atom is, you are changing the number of protons in the atom.

So I would say, Yes, a proton can react and leave the atom.

\(17+9=26\)

A single day has 86,400 seconds in it. So we divide \(\frac{565,900}{86,400} =\) 6.54976851852 Days.

Yes, 49 is the correct answer.

For this specific problem, you are multiplying:   7x7=49

For say \(5^8\) what you do is multiply 5x5x5x5x5x5x5x5= 390,625

The little number shows how many times you multiply and the big number shows what you are multiplying.

If pie = 3.14 then 3.14+3.14= 6.28

If pie = an actual pie, then pie+pie= 2 pies. (yum!)

If pie = \(\pi \) then \(\pi + \pi = 2\pi \)

Hope that helps!

\(\dbinom{16}{5}=\dfrac{16\times 15\times 14\times 13\times 12}{5\times 4\times 3\times 2\times 1}=\boxed{4368}\)

And that's how it's done.

Here is the full answer:

\(\begin{align*} \dbinom{15}{2} &= \dfrac{15!}{13!2!} \\ &= \dfrac{15\times 14}{2\times 1} \\ &= 15 \times \dfrac{14}{2} \\ &= 15 \times 7 \\ &= \boxed{105}. \end{align*}\)

Sorry, yes there was, but I got the problem now. Thanks!
