Question

x= 1³ + 2³ + 3³ + 4³ + 5³ + 6² + 7² + 8² + 9²

me ajudem pfv

Answer 1

x = 1³ + 2³ + 3³ + 4³ + 5³ + 6² + 7² + 8² + 9²

x = 1 + 8 + 27 + 64 + 125 + 36 + 49 + 64 + 81

x = 9 + 91 + 161 + 113 + 81

x = 100 + 274 + 81

x = 374 + 81

x = 455

Answer 2

1³ = 1 x 1 x 1 = 1

2³ = 2 x 2 x 2 = 8

3³ = 3 x 3 x 3 = 27

4³ = 4 x 4 x 4 = 64

5³ = 5 x 5 x 5 = 125

6² = 6 x 6 = 36

7² = 7 x 7 = 49

8² = 8 x 8 = 64

9² = 9 x 9 = 81

1 + 8 + 27 + 64 + 125 + 36 + 49 + 64 + 81 = 455
