Question

Esqueva a matriz A=(Aij)3×3 na qual Aij=I+J

Answer 1

( a₁₁ a₁₂ a₁₃ )

( a₂₁ a₂₂ a₂₃ )

( a₃₁ a₃₂ a₃₃ )

a₁₁ = 1 + 1 = 2

a₁₂ = 1 + 2 = 3

a₁₃ = 1 + 3 = 4

a₂₁ = 2 + 1 = 3

a₂₂ = 2 + 2 = 4

a₂₃ = 2 + 3 = 5

a₃₁ = 3 + 1 = 4

a₃₂ = 3 + 2 = 5

a₃₃ = 3 + 3 = 6

( 2 3 4 )

( 3 4 5 )

( 4 5 6 )
