$$4\sqrt{27}=4\sqrt{9*3}=4*3*\sqrt3=12\sqrt3$$
That is sweet Rosala, you must have a day for EVERYTHING in India.
Λυπάμαι, αλλά η μετάφραση δεν έχει νόημα.
Thanks Chris.
The forum calc uses $$atan\;1.345$$ but a more common notation (meaning exactly the same thing) is $$tan^{-1}1.345$$
Please note: the forum calc is on the home page.
No I've changed my mind - I still dont understand.
What did you run through Wolfram Alpha?
Chris, I do not understand what is being asked. Can you explain it to me?
Pardon?
The question is done.
Do you need me to show you how to do the division?
I assume that you can do the expansion yourself.
Why don't you do the expansion, put the answer to that up and if you need me to I can help you with the algebraic division.
Otherwise tell me what your problem really is. :)
ln3, ln9, ln27, ln81, ...
$$ln3^1,\;\;ln3^2,\;\;ln3^3,\;\;ln3^4,\;\;.....ln3^n$$
The nth term is ln3^n which is the same as n*ln3
The absolute value is the distance from 0 on the number line.
So positive numbers stay positive
and negative numbers become positive.
