Question

write the order of magnitude of following
numbers
(a )49
(b )6x 108​

Answer 1

Answer:

Explanation:

We can write 49 as 4.9×10  

1

 

Since 4.9 is lesser than 5.

Hence, its order of magnitude will be 1.  

For 51 :  

We can write 51 as 5.1×10  

1

 

Since 5.1 is greater than 5, so it is more closer to 10 than 1.

Hence, its order of magnitude will be 2.  

Therefore, the order of magnitude of 49 and the order of magnitude of 51 differs by 1.
