Given
, cubing the cube root of 91
results in
, which simplifies to 9. Therefore, the final answer is a = 9.
Let's break down the calculation step by step:
Given
:
1. Cube the Cube Root of 91:
![\[a = (\sqrt[3]{91})^3 = \sqrt[3]{91^3}\]\\](https://img.qammunity.org/2024/formulas/mathematics/high-school/dnxn570ebwiyeh8hqwyopg3280e9b5u5qd.png)
2. Evaluate the Cube:
![\[\sqrt[3]{91^3} = \sqrt[3]{729}\]](https://img.qammunity.org/2024/formulas/mathematics/high-school/pf8mwt11cq9ikrpk1vc5ivdk0b95uba6ov.png)
3. Determine the Cube Root:
![\[\sqrt[3]{729} = 9\]](https://img.qammunity.org/2024/formulas/mathematics/high-school/c3602q5a6v7t1hn4nol2i989ff941ya1os.png)
Therefore, the solution to a is a = 9. Each step involves basic operations, starting with cubing the cube root and simplifying until we arrive at the final result, which is 9.
