For this case, the first thing you should know is that a number in scientific notation is a number of the form:
 [tex]a * 10 ^ b [/tex]
 Where,
 a: is a number between 1 and 10
 b: is the exponent of the scientific notation.
 We have then that the number that is in scientific notation written correctly is:
 [tex]6x10 ^ {11}[/tex]
 Answer:
 [tex]6x10 ^ {11}[/tex]

Answer: [tex]6\times10^{11}[/tex]

Step-by-step explanation:

We know that the scientific notation is a technique to write a very large or a very small number in the product of a decimal form of  number [generally between 1 and 10]and powers of ten.

[tex]6\times10^{11}\\\text{ It is in scientific form}\\\\12\times10^{-8}\\\text{It is not in scientific form, since} 12 >9\\\\0.2\times10^5\\\text{It is not in scientific form, since }0.2<1\\\\8\times7^2\\\text{ It is not in scientific form, since power of 10 is not there}[/tex]

Hence, the number written in scientific notation is [tex]6\times10^{11}[/tex]
