Answer 1

Typo is there, right? x =332, y = 333, not x =333, right?

Answer 2

good catch

Answer 3

I have to solve this within a minute

Answer 4

Let's wait for @imqwerty

Answer 5

a^3 + b^3 + c^3 – 3abc = (a+b+c)((a-b)^2 + (b-c)^2 + (c-a)^2) /2

use this

Answer 6

wow how did he get that thing

Answer 7

the traditional method may take an hour

Answer 8

or their might be some other trick using

\(y=x+1,z=x+2\)

Answer 9

What is the traditional method?

Answer 10

(traditional method)putting all those values and calculating

Answer 11

a^3 + b^3 +c^3 = (a+b+c)(a^2 +b^2 +c^2 -ab -bc -ca)
=(a+b+c)(a^2 +a^2 +b^2 +b^2 +c^2 +c^2 -2ab-2bc-2ca)/2

did u get it now

Answer 12

yes i always forget the formula within 2 days
