The answer is C because she did write associative instead of distributive in step 2 in which made her work error.
Car 2 will drive faster im not sure but thats my answer
Answer:
![\boxed{\boxed{\sqrt[3]{d}\cdot \sqrt[3]{d}\cdot \sqrt[3]{d}=d}}](https://tex.z-dn.net/?f=%5Cboxed%7B%5Cboxed%7B%5Csqrt%5B3%5D%7Bd%7D%5Ccdot%20%5Csqrt%5B3%5D%7Bd%7D%5Ccdot%20%5Csqrt%5B3%5D%7Bd%7D%3Dd%7D%7D)
Step-by-step explanation:
The given expression is,
![=\sqrt[3]{d}\cdot \sqrt[3]{d}\cdot \sqrt[3]{d}](https://tex.z-dn.net/?f=%3D%5Csqrt%5B3%5D%7Bd%7D%5Ccdot%20%5Csqrt%5B3%5D%7Bd%7D%5Ccdot%20%5Csqrt%5B3%5D%7Bd%7D)
It can also be written as,

The exponent product rule of algebra states that, while multiplying two powers that have the same base, the exponents can be added.
As here all the terms have same base i.e d, so applying the rule





The answer is D.
Hope I helped
