    (9x²) ²

    Step-by-step explanation:

    Given the expression 81x⁴, to write the expression as a square of a monomial, first we will assign a variable to the expression.

    y = 81x⁴

    Then we take the square root of both sides of the expression

    √y = √81x⁴

    y^½ = √81 * √x⁴

    y^½ = 9x²

    Squaring both sides of the resulting equation to get y back

    (y^½) ² = (9x²) ²

    y = (9x²) ²

    The expression as a square of a monomial is (9x²) ²
