Question

Need help with 76 and 78 please. Thank you . I will give a Brainly and extra points.

Answer 1

Answer:

9 and 65

Step-by-step explanation:

76

N(A×B)=N(B×A)

Since multiplication is a commutative

A=[d,o,g] B=[p,i,g]

A×B=[(d,p),(d,g),(d,i),(o,i),(o,g),(o,p),g,p)(g,i),(g,g)]

n[A×B]=9

78

13×5=65
