Understand the problem: Understand the problem.We need to find the value of the cube root of 2 divided by the cube root of −128.
Apply cube root: Apply the cube root to both the numerator and the denominator.3−12832=3−1282
Simplify fraction: Simplify the fraction inside the cube root. −1282 can be simplified to −641 because 2 divided by 128 is 641 and we keep the negative sign.3−1282=3−641
Evaluate cube root: Evaluate the cube root of −641. The cube root of −1 is −1 because (−1)×(−1)×(−1)=−1. The cube root of 64 is 4 because 4×4×4=64. Therefore, 3−641=−41.
