Question

If a = 12, b = 34, verify the following:

(i) a × b = b × a

(ii) a + b = b + a​

Answer 1

A*b=b*a
12*34=34*12
408=408, verified

A+b=b+a
12+34=34+12
46=46, verified

Answer 2

i ) a × b = b × a

• Putting the values

• a = 12
• b = 34

→ a × b = b × a

→ 12 × 34 = 34 × 12

→ 408 = 408

→ LHS = RHS

• Hence varified

______________________________________

(ii) a + b = b + a

• Putting the values

• a = 12
• b = 34

→ a + b = b + a

→ 12 + 34 = 34 + 12

→ 46 = 46

→ LHS = RHS

• Hence Varified
