Question

Answer the following Questions
5) verify that (-21)*(-4)+(-6)| ||-21)*(-411 +14-21)*|-6). Justify your answer
6) Write the properties of integers under addition.​

Answer 1

Answer:

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

Step-by-step explanation:

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
