x = (2^3)^33 : [ (2^2)^32 * 2^34 + (2^25)^5 : (2^4 * 2^23) + (7 + 1)^32 * 4]
x = 2^99 : [ 2^64 * 2^34 + 2^125 : 2^27 + 8^32 *2^2]
x = 2^99 : ( 2^98 + 2^98 + (2^3)^32 * 2^2)
x = 2^99 : (2^98 + 2^98 + 2^96 * 2^2)
x = 2^99 : (2^98 + 2^98 + 2^98)
Dam factor comun pe 2^98:
x = 2^99 : [2^98(1 + 1 +1)]
x = 2^99 : (2^98 * 3)
x = (2^99 : 2^98) * 3
x = 2 * 3
x = 6
