Physics Algebra Cancelling Help

In summary, the question asks for the process of canceling terms in the equation Ve = sqrt 2(mu)/r where mu is the product of the Gravitational Constant and the mass of the object to be escaped from. The recommended approach is to use consistent units and to solve algebraically until the desired quantity is isolated before plugging in the given numbers.

Homework Statement


I need to know how to cancel terms in the equation Ve = sqrt 2(6.6742 x 10^-11 N m^2 / kg^2 (12.1kg))/0.106780959m


Homework Equations



Ve = sqrt 2(mu)/r

Where r is the distance from the denter of the object to be escaped from, and mu is the Gravitational Constant multiplied by the mass of the object to be escaped from.

The Attempt at a Solution



I really have no idea where to start...

if u know what the end units are supposed to be, you can ignore units while solving the problem and just add the proper units to your final answer.

but if u do this, make sure all the units are consistent.

You cannot cancel numbers.

Solve your problem algebraically, until you have isolated the quantity you need. Then, finally, the LAST step you use the numbers given.

You will need to post a better problem statement to get help.

Edit:
The approach suggested by Pakmingki, is a bad one. You would be much better off to let the units guide your algebra.
