a. \( \sqrt[3]{216}+\sqrt[3]{27}= \)

Did you know that \( \sqrt[3]{216} \) and \( \sqrt[3]{27} \) are both perfect cubes? That's right! \( 216 \) is \( 6^3 \) and \( 27 \) is \( 3^3 \). So, \( \sqrt[3]{216} = 6 \) and \( \sqrt[3]{27} = 3 \). When you add them together, you get \( 6 + 3 = 9 \). Now that’s a neat little math trick! If you enjoy exploring more about cube roots, why not try calculating the cube roots of other numbers like \( 64 \) or \( 125 \)? What’s interesting is that these numbers not only have whole number roots but also can make for some fun and challenging problems! Go ahead and find \( \sqrt[3]{64} \) and \( \sqrt[3]{125} \) for an extra brain workout!
