Math Problem Statement

Select all the expressions equivalent to (4x2)3.

Answer choices:

12x5

64x6

82 • x6

64x5

16x6

Solution

We need to simplify the expression (4x2)3(4x^2)^3.

Step-by-step simplification:

  1. Apply the exponent rule: (ab)n=anbn(a \cdot b)^n = a^n \cdot b^n, which means the exponent applies to both 4 and x2x^2.

    (4x2)3=43(x2)3(4x^2)^3 = 4^3 \cdot (x^2)^3

  2. Simplify each part:

    • 43=644^3 = 64
    • (x2)3=x23=x6(x^2)^3 = x^{2 \cdot 3} = x^6
  3. Combine the results: (4x2)3=64x6(4x^2)^3 = 64x^6

Now, compare this with the answer choices:

  • 12x⁵: Not equivalent.
  • 64x⁶: Equivalent.
  • 82 • x⁶: Not equivalent (the coefficient is incorrect).
  • 64x⁵: Not equivalent (the power of xx is incorrect).
  • 16x⁶: Not equivalent (the coefficient is incorrect).

Correct answer:

  • 64x⁶
