Final answer:
The expression in radical form for (7x³y²)²⁷ is 7²⁷ * x^(327) * y^(227), which simplifies to 7²⁷ * x⁸¹ * y⁵⁴.
Step-by-step explanation:
To express the given expression (7x³y²)²⁷ in radical form, we apply the power property of exponents, which states that when an expression with an exponent is raised to another exponent, we multiply the exponents.
(7x³y²)²⁷ = 7²⁷ * x^(327) * y^(227)
Solving the exponents within the parentheses, we get: 7²⁷ * x⁸¹ * y⁵⁴
Therefore, the final result of the expression in radical form is 7²⁷ * x⁸¹ * y⁵⁴, which corresponds to option C) 49x^81y^54.
