Find the cube root of 81: ^3√81
1. -9
2. 27
3. ^3√81
4. 9
4. 9
The cube root of 81 is calculated as follows:
The cube root of 81 is ^3√81.
So the answer is option 3, ^3√81.
To find the cube root of 81, you need to evaluate the expression ^3√81.
The cube root of a number x is a value that, when raised to the power of 3, equals x. So, you need to find a number that, when cubed, equals 81.
To solve this, you can use a calculator or manually try different numbers to see if they satisfy the condition. However, since this is a multiple-choice question, you can simply evaluate the options provided to find the correct answer.
Let's calculate the cube of each option:
1. (-9)^3 = -9 * -9 * -9 = -729
2. 27^3 = 27 * 27 * 27 = 19683
3. (^3√81)^3 = 81
4. 9^3 = 9 * 9 * 9 = 729
As you can see, the only option that satisfies the condition is option 3, ^3√81. Therefore, the cube root of 81 is ^3√81.
