Show that m(2r'a' +ra'')=0 can be rewritten as md/dt(r^2*a')=0
Has anyone got any tips on how i should go about this?? Thanks x

Rearranging equations allows us to manipulate mathematical expressions in order to solve for a different variable or to simplify the equation. This can be helpful in solving complex problems or in finding relationships between different variables.
Rearranging an equation is necessary when we need to solve for a specific variable or when the equation is too complicated to solve in its current form. It is important to identify the desired variable and follow the correct steps to rearrange the equation.
The general steps to rearrange an equation are: 1) Identify the variable that you want to solve for; 2) Isolate that variable on one side of the equation using inverse operations; 3) Simplify the equation as much as possible; 4) Check your answer by plugging it back into the original equation.
In general, yes, you can rearrange most types of equations as long as they follow the basic rules of algebra. However, some equations may be more complex and require more advanced techniques for rearranging.
One common mistake to avoid is not performing the same operation on both sides of the equation. This can lead to an incorrect solution. It is also important to pay attention to the order of operations and to keep track of any negative signs when rearranging.
