Final answer:
In this expression, x³ * x³ * x³ is not equivalent to x³ * 3 * 3. When we have the same base number raised to different exponents and those expressions are multiplied, we add the exponents together.
Step-by-step explanation:
In this expression, x³ * x³ * x³ is not equivalent to x³ * 3 * 3.
When we have the same base number raised to different exponents and those expressions are multiplied, we add the exponents together. So, x³ * x³ * x³ can be simplified as x^(3+3+3) = x^9.
On the other hand, x³ * 3 * 3 can be simplified as 3^(1+1) = 3^2.
Therefore, x³ * x³ * x³ is equivalent to x^9 and not to x³ * 3 * 3.
