P=C*G^Y
divide both sides by C
take the log of both sides
look up log laws and decide what to do next
I think you will find the log law on the forumulary page page.

4n-2 +7n=2
4n+7n-2=2
11n-2=2
add 2 to both sides
11n=4
n=4/11
Just add however many zeros there are onto the end of the other number.
$$\sqrt{90a^3b^8}\\\\ =\sqrt{90}\sqrt{a^3}\sqrt{b^8}\\\\ =\sqrt{9}\sqrt{10}\sqrt{a^2}\sqrt{a}\sqrt{b^8}\\\\ =3\sqrt{10}\;a\sqrt{a}\;b^4\\\\ =3ab^4\sqrt{10a}\\\\$$
$$4i\sqrt{5}$$
1/2*21+1/8
type it straight into the calc on the home page.
You put the 12 where the x is
-2*12+4
Just type this into the calc on the home page
Caroline you really need to get an account here. It is very easy you do not have to give any personal information at all. Once you have an account then you will have access to our private message system and you will be able to chat privatly to other members. When you are talking to an anonymous person you don't really know if it is the same one each time. If you befriend a member then they will be the only one who can use their username so you will know better who you are talking with.
We need more information than this. sorry.
