Question

if a={2,3,4} b={-1,2,5} and c={3,5} find a×{b-c}.​

Answer 1

Step-by-step explanation:

a={2,3,4} b={-1,2,5} c={3,5}

a×{b-c}

={2,3,4}×[{-1,2,5}-{3,5}]

={2,3,4}×{-1,2}

={2,-1},{2,2},{3,-1},{3,2},{4,-1},{4,2}

Answer 2

$\huge\tt\colorbox{lightblue}{Answer}$

a = {2 , 3 , 4}

b = {-1 , 2 , 5}

c = {3 , 5}

{b - c} = {-1 , 2 , 5} - {3 , 5}

{b - c } = {-1 , 2}

a × {b - c} = {2 , 3 , 4} × {-1 , 2}

a × {b - c} = {2 , -1} {2 , 2} {3 , -1} {3 , 2}

{4 , -1} {4 , 2}
