Answer:

[tex]5.5\times 10^{-1}[/tex]

Step-by-step explanation:

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

[tex]\dfrac{6.8\times 10^3-7.2\times 10^2}{1.1\times 10^4}[/tex]

We can solve it as follows :

[tex]=\dfrac{6800-720}{11000}\\\\=\dfrac{6080}{11000}\\\\=0.55[/tex]

or

[tex]=5.5\times 10^{-1}[/tex]

So, the required answer is equal to [tex]5.5\times 10^{-1}[/tex].
