Question

X = (ai j) 4×2 de modo que ai j=2i^2-j​

Answer 1

Resposta:

X = x11 x12

x21 x22

x31 x32

x41 x42

x11 = 2.1^2-1

x11 = 2^1

x11 = 2

x12 = 2.1^2-2

x12 = 2^0

x12 = 1

x21 = 2.2^2-1

x21 = 4^1

x21 = 4

x22 = 2.2^2-2

x22 = 4^0

x22 = 1

x31 = 2.3^2-1

x31 = 6^1

x31 = 6

x32 = 2.3^2-2

x32 = 6^0

x32 = 1

x41 = 2.4^2-1

x41 = 8^1

x41 = 8

x42 = 2.4^2-2

x42 = 8^0

x42 = 1

X = 2 1

4 1

6 1

8 1
