Question

Verify the property a × b = b × a by taking a=3/11 and b= -5/9
with proper explanation

Answer 1

Step-by-step explanation:

To    Verify  the  following 

(−21)×[(−4)+(−6)]=[(−21)×(−4)]+[(−21)×(−6)]

Taking   LHS   we   have  

(−21)×[(−4)+(−6)]

=(−21)×[−4−6]

=(−21)×(−10)

=210

Now ,  Taking   RHS   we   have  

[(−21)×(−4)]+[(−21)×(−6)]

=84+126

=210

Hence ,   LHS  =   RHS

Answer 2

Answer:

$a \times b = b \times a$

$\frac{ 3}{11} \times \frac{ - 5}{9} = \frac{ - 5}{9} \times \frac{3}{11}$

Now we see that 3 x 3 is 9

therefore,

$\frac{1}{11} \times \frac{ - 5}{3} = \frac{ - 5}{3} \times \frac{1}{11}$

$\frac{ - 5}{33} = \frac{ - 5}{33}$

$hence \: lhs = rhs$

$property \: is \: verified$
