Question

Considere a matriz m=[aij]3x3, tal que aij=3i-j escreva a matriz m​.

Answer 1

Resposta:

m = ( m11 m12 m13 )

( m21 m22 m23 )

( m31 m32 m33 )

m11 = 3.1+1

m11 = 3+1

m11 = 4

m12 = 3.1+2

m12 = 3+2

m12 = 5

m13 = 3.1+3

m13 = 3+3

m13 = 6

m21 = 3.2+1

m21 = 6+1

m21 = 7

m22 = 3.2+2

m22 = 6+2

m22 = 8

m23 = 3.2+3

m23 = 6+6

m23 = 9

m31 = 3.3+1

m31 = 9+1

m31 = 10

m32 = 3.3+2

m32 = 9+2

m32 = 11

m33 = 3.3+3m33 = 9+3

m33 = 12

m = ( 4 5 6 )

( 7 8 9 )

( 10 11 12 )
