Answer:
11\text{x}^(3)\text{y}^(4)

=====================================

Work Shown:


\left(121\text{x}^6\text{y}^8\right)^(1/2)\\\\\left(121\right)^(1/2)*\left(\text{x}^6\right)^(1/2)*\left(\text{y}^8\right)^(1/2)\\\\√(121)\text{x}^(6*(1/2))\text{y}^(8*(1/2))\\\\11\text{x}^(3)\text{y}^(4)\\\\

Therefore,


\left(121\text{x}^6\text{y}^8\right)^(1/2)=11\text{x}^(3)\text{y}^(4)\\\\

Step-by-step explanation:

The exponent of 1/2 represents a square root. This is how
(121)^(1/2) turned into
√(121) which then simplified to 11.

As for the variable terms, we multiply that outer exponent 1/2 with each exponent inside the parenthesis. Think of it like the distribution rule. It's not really distribution, but similar.

Recall that
(a^b)^c = a^(bc)
