answer : 2nd one
Step-by-step explanation:
All its asking is for you to write an equation
The simplest radical form is 
Explanation:
The expression is 
To determine the radical form, let us write the number 68 as a product of prime factors.
Thus, we have,

Since, 2, 17 are prime factors and hence, no further factorization is possible.
Hence, it can be written as,

Applying the radical rule
, we have,

Simplifying, we have,

Thus, the simplest radical form is
