Let’s solve each problem one by one. We’re finding square roots (√) and cube roots (∛). Remember:
- Square root of a number is what you multiply by itself to get that number.
Example: √81 = 9 because 9 × 9 = 81.
- Cube root of a number is what you multiply by itself three times to get that number.
Example: ∛64 = 4 because 4 × 4 × 4 = 64.
Now let’s go through each problem carefully.
