The simplest radical form is
Step-by-step 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
