Answer 1

Vedic Maths. It's the best option, and very different from the usual grind. I do not know any site, though, you will have to go to google search.

Answer 2

Actually I looked at it again and it's crap.

This statement:

it is impossible to write
a^(n)-b^(n)=x^(n)
for n>2.

Is false. For one, there is the obvious situation where a=b=1, and x=0. In this case:

a^n-1^n=0^n will dissolve to

1-1=0, which is true, no matter what n you have.

However, your equation fails even when unique non zero or one numbers are placed into it.

Consider the following. Substitute a=14, b=7 and n=3 (therefore n>2). Then we have the equation:

14^3-7^3=x^3.

By cubing a and b, we reach:

2744-343=x^3
2401=x^3

By taking the cube root of 2401:

(2401)^(1/3)=x [taking the power of 1/3 is the equivalent of taking the cube root]

2401^(1/3)=(7)*(7)^(1/3). The decimal approximation of this number is 13.390518279407.


Therefore, 14^3-7^3=[(7)(7)^(1/3)]^3. You can test this yourself by checking 14^3-7^3 and 13.390518279407^3 on your calculator [The majority of calculators only use 10 digits for calculations, so this decimal approximation will give you the exact answer of 2401].


Notes: If you were to restrict your set to all numbers where a and b cannot equal 1, and you were to restrict it such that a, b and x have to be integers, it may be true; I, however, neither have the time nor the curiosity to see if this holds. In your current statement, though, you have not applied these restrictions, and therefore your current statement is false.

Do not say that "It should be assumed" or "it's obvious that..." as an attempt to explain this lack of data; without explicitly saying otherwise, in mathematics we always assume that any number can be used and the set of numbers being used is real numbers. If you want to restrict either of these, you MUST explicitly state it.

Answer 3

i hate math !!!

Answer 4

dang......that's crazy!
