Hi i am having trouble with this question:

(2g)3

Thanks :)

First, that is not a question (nor a function nor an equation), it is an 'expression'. What do you want to do with that expression? And what does that subscript mean?

If it were a superscript, \(\displaystyle (2g)^3\), and you wanted to 'simplify' it or 'multiply it out', then it would mean \(\displaystyle (2g)(2g)(2g)\) which is the same as \(\displaystyle [(2)(2)(2)ggg\). I assume you can multiply those "2"s. Without knowing what "g" is we can do no more than write it as \(\displaystyle g^3\).

Hope this helps

(2g)^3 = 2g*2g*2g Since the exponent 3 means that you multiply 2g three times.
= 2*2*2* g^3 You just multiply the numbers together, and the variables together.
= 8 * g^3.

It means 3gX3gX3g=9[FONT=MathJax_Math]g3

You can place the value of the variable g and get the result...

Please don't try to help people when you need major help yourself...
 
There was no "attempt to help" there. The entire point of the post was to put that link here. It was spam. There should be a way of preventing people with, say, less than 10 posts, from posting links.
 
Ah, I stopped looking at that post as soon as I saw 3g :p

may be "g" is the acceleration due to gravity. .9.81 m/s2​. .
