To find the cube root of 81, you can use the ∛ (cube root) symbol.
The cube root of 81 is written as ∛81.
Now, let's calculate it step-by-step.
1. Starting with 81, the cube root asks "what number can I multiply by itself three times to get 81?"
2. Let's find the root. We need to find the number that when multiplied by itself three times, gives us 81.
3. The cube root of 81 is 4 because 4 × 4 × 4 = 64.
So, the cube root of 81 is 4.
To find the cube root of 81, you can follow these steps:
1. Start by writing down the symbol for cube root, which looks like this: ^3√.
2. Then, write down the number 81 under the cube root symbol.
3. Finally, simplify the expression by finding the number that, when cubed, equals 81. In this case, the cube root of 81 is 4.
