10. ### simplify equation as far as possible

http://i1174.photobucket.com/albums/r601/warlacozte/foumlrenkla_zps9f3a09e6.png so I'm thinking i should use (a+b)(a-b)=a^2-b^2 rule, but i don't really know what to do with the 3 in the beginning. or maybe just take the entire thing squared
11. ### Simplify and solve

Helping my middle schooler and got hung up with this one. Simplify and solve: (630*137+2) / (316+315*136) I don't see it. Extract 2 from the numerator? Then what? Any guidance is appreciated.
12. ### How do I simplify this?

We are given this and asked to simplify, in the other questions the numbers have a common large denomenator that has a clean square root but in this one they do not. I have no examples to work with and I have a quiz tomorrow so I could really use an answer

14. ### simplify

How to prove $$\frac{-2sinA}{1-cosA}cos(A/2)tan^{-1}cos(A/2)=\frac{\pi^2-4A^2}{8}$$
15. ### Simplify expression for faster calculation

Is there any way to simplify the expression below? I want to calculate it many times in real time so speedier is better. What I really want is m, but it cannot be solved for, so I use a numerical method. The simplification I can think of is to calculate recurring parts of the expression only...
16. ### (Factorials) How should I simplify this?

n![(1/n-1)! - (1/n!)] The correct answer is apparently n-1, but I keep getting a different answer. This is what I did: n![(n!-(n-1)!)/(n-1)!(n!)] =n/(n-1)! Could somebody please show me what I've done wrong or what I need to do differently? :) any help really appreciated! :)
17. ### Simplify the Trinomial

How can I simplfy the trinomial 3x^3 + 5y^3 + 14? Is this the sum of cubes? If so, how is it done? Further instructions say to write CANNOT BE SIMPLIFIED if that is the case. I say this cannot be simplified more than it is. Am I correct?
18. ### How to simplify?

Prove x^(1/3)+(2x-3)^(1/3)=(12(x-1))^(1/3) I am totally stuck. How would I edit the left hand side to look like the right hand side? Is it to do with (A+B)^3 or (A^3+B^3)? I can't seem to see the pattern! Edit: WAIT! Never mind! I understand now! :D
19. ### How to simplify an equation?

Hello, I have the following problem. There are known dependencies between variables. a = a1 + a2. C = C1 + C2. C = \frac{a}{{{{\left( {1 + d} \right)}^t}}},C1 = \frac{{a1}}{{{{\left( {1 + d1} \right)}^t}}},C2 = \frac{{a2}}{{{{\left( {1 + d2} \right)}^t}}}. The desired quantity is d. In...
