Answer 2

Answer: (b) -45 ¢ 100 + - 45 ¢ 8

Step-by-step explanation:

• We have to judge in which form we cannot write {- 45} ¢ 108.
• Checking option (a)

         - 45 ¢ {100 + 8}

     ⇒ -45 ¢ 108

So, we can write the above expression in this way.

• Checking option (b)

         -45 ¢ 100 + - 45 ¢ 8

     ⇒-45 ¢ 100-45 ¢ 8

    ⇒ -45 ¢ 55 ¢8

So,we cannot write the above expression in this way.

• Hence,the correct option is option (b).
