Solution:

1. Start with the equation:

X^2 = 81^{\frac{1}{2}}

2. Recognize that81^{\frac{1}{2}} is the square root of 81:

81^{\frac{1}{2}} = \sqrt{81}

3. Calculate the square root of 81:

\sqrt{81} = 9

4. Substitute back into the equation:

X^2 = 9

5. Solve forX by taking the square root of both sides:

X = \pm \sqrt{9}

6. Simplify the result:

X = \pm 3

7. Thus, the solutions forX are:

X = 3 and X = -3
