Final answer:
The expression (4g³h²k⁴)³ simplifies to 64g⁹h⁶k¹².
Step-by-step explanation:
The expression (4g³h²k⁴)³ can be simplified by applying the exponent to each term within the parentheses. When you raise a power to a power, you multiply the exponents. Using this rule, we get:
(4³g³³) * (h²³) * (k⁴³)
This simplifies to:
64g⁹h⁶k¹²
Therefore, the equivalent expression is option a) 64g⁹h⁶k¹².
