Question

Efectuati:
(1-1^2)•(1-1^3)•(1-1^4)•...•(1-1^50)
Va rog ajutati-ma​

Answer 1

$(1 - {1}^{2} )(1 - {1}^{3} )...(1 - {1}^{50} ) \\ = (1 {}^{2} - {1}^{2} )(1 {}^{2} - {1}^{3} )...(1 {}^{2} - {1}^{50} )$

1 la orice putere este 1. așa ca:

$= (1 - 1)(1 - 1)...(1 - 1) \\ = 0\cdot0\cdot0\cdot...\cdot0 \\ = 0$
