Explicație pas cu pas:
(-2)²x3³ + (-3)³x4⁴ + .....+(-99)⁹⁹x100¹⁰⁰ +
+ 2²x(-3)³+ 3³x(-4)⁴+.....+99⁹⁹x(-100)¹⁰⁰ = ?
(-2)²x3³+(-3)³x4⁴+ .....+(-99)⁹⁹x100¹⁰⁰+2²x(-3)³+3³x(-4)⁴+.....+99⁹⁹x(-100)¹⁰⁰ =
= 2²x3³-3³x4⁴+.....-99⁹⁹x100¹⁰⁰ -2²x3³+3³x4⁴+........+99⁹⁹x100¹⁰⁰ =
= (2²x3³-2²x3³)+(-3³x4⁴+3³x4⁴) +.....+(-99)⁹⁹x100¹⁰⁰+99⁹⁹x100¹⁰⁰) = 0
