I am having issues trying to grasp how to rearrange formulas in the correct order. I'm not sure in what order I have to rearrange a formula. A particular formula which I am struggling to rearrange correctly so l is the subject is:

T = 2π√(l÷g)....................Those parentheses ( ) are very important!!!

Thanks in advance.

What have you tried? We are willing to help you but we need to know what type of help you need. After reading the posting guidelines did you really thin think that we would just give you the answer?

Can you solve this problem for I? T = 2√l÷4

Post back showing your work so we can help you solve your problem.

Start with "squaring" both sides of the given equation.

How do you know there are parenthesis where you placed them? Is this a known formula? If yes, then please tell me more about it.

If T is time, I is length and g is acceleration - then "dimensional analysis" will tell you that.
A Google search on" pendulum" would be fruitful.
