Question

(6.8 X103)-(7.2 X 10)
1.1 X 104
X 10

Answer 1

`5.5* 10^(-1)`

Explanation:

We need to find the value of the given expression i.e.

`(6.8* 10^3-7.2* 10^2)/(1.1* 10^4)`

We can solve it as follows :

`=(6800-720)/(11000)\\\\=(6080)/(11000)\\\\=0.55`

or

`=5.5* 10^(-1)`

So, the required answer is equal to
`5.5* 10^(-1)`.
