Please describe the process properly. I will mark you Brainliest .

Answer 1

Answer:

a={4,5,6} ; b={5,6}

Step-by-step explanation:

a * b is a Cartesian product

that is

if a={x,y} b={z}

a * b={ (x,z) ; (y,z) }

Answer 2

Answer:

$\sf \: a \times b = {\{(4,5) (4,6) (5,5) (5,6) (6,5) (6,6) \}}$

• We see that elements of a are 4,5 and 6 because a come first in multiple therefore it's elements come first in answer.
• And elements of b are 5 and 6 because b come second in multiple therefore it's elements come second in answer.
