Worked through step by step. More quadratics.

Answer
27x6y3\boxed{27x^6 y^3}

Checking by expanding the product gives (3x2y)(3x2y)(3x2y)=(333)(x2x2x2)(yyy)=27x6y3(3x^2y)(3x^2y)(3x^2y) = (3 \cdot 3 \cdot 3)(x^2 \cdot x^2 \cdot x^2)(y \cdot y \cdot y) = 27x^6y^3, which confirms the result.

Problem: Simplify the expression (3x2y)3(3x^2 y)^3.

Steps

  1. Apply the power of a product rule
    33(x2)3y33^3 (x^2)^3 y^3
  2. Evaluate the numerical power
    27(x2)3y327 (x^2)^3 y^3
  3. Apply the power of a power rule
    27x23y327 x^{2 \cdot 3} y^3
  4. Simplify the exponent
    27x6y327 x^6 y^3
