Julo considers the reaction of the triangle
What is the correct cross product that he should use to solve for the missing dimension?
(12) = 217
821) = 122
(128) = 12%
(1221) = x

answer: t=3

\3. yes the presentation (i.e. odd numbers being written as differences of two squares) is possible for all odd natural number however the presentation may not be unique. for example,  57=112−82=292−28257=112−82=292−282.

\4. 2 can't be written as a difference of two squares because 4-1=3 and 1-1=0 and the difference of squares grows to integers larger that 3.

can i get some in proving questions 1 and 2?
