Philosophus Rex - welcome to GMATClub.

You are an active member and we are happy to see you here. Wanted to show you a few quick shortcuts to post math expressions that are easier to read for everyone, similar to how Nookway responded to your questions.

To create a math formula, most of the time all you have to do is select the expression and hit the M button (located under the B, I, U buttons in the Message Posting screen)

Here is what I did to convert your posts to math-friendly format -mostly just add an M-Tag on both sides of the expression. Feel free to contact me if you have any questions!

**Code:**

2. If [m]5^21 * 4^11 = 2 * 10^n[/m]what is the value of n?

Is there any page you can recommend for learning how to deal with [m]A^x + B^y and a^x * B^y[/m]? Im clueless regarding these.

3. [m][fraction]((8^2)(3^3)(2^4))/96^2[/fraction][/m]
