Question

Verify that a+b = b+a for each of the following. a= -2 /9, b= - 4/3​

Answer 1

GivEn

• a= -2 /9
• b= - 4/3

To find:

• a + b = b + a

Solution:

a + b = b + a

Where,

• a= -2 /9
• b= - 4/3

⠀⠀━━━━━━━━━━━━━━━━━━━⠀

« Putting the values in the given Equation,

→ a + b = b + a

→ -2/9 + (-4/3) = -4/3 + (-2/9)

→ -2/9 - 4/3 = -4/3 - 2/9

→ -2 - 12/9 = -2 - 12/9

→ -14/9 = -14/9

LHS = RHS

Hence, Verified!
