5. Find the cube root of 81: ^3√81
A. ^3√81
B. -9
C. 27
D. 9
C. 27
it was a u dumb
I apologize if my previous response was incorrect or unclear. The cube root of 81 is 4.3267487109222245.
To find the cube root of 81, we need to find the number that, when raised to the power of 3, gives us 81.
The correct answer is C. 27.
If we take 27 and raise it to the power of 3: 27^3 = 27 × 27 × 27 = 729 × 27 = 19683.
Therefore, the cube root of 81 is 27.
To find the cube root of 81 (denoted as ^3√81), you can use a calculator or perform the calculation manually.
If you want to calculate it manually, you can start by guessing a number, cubing it, and comparing it to 81 to see if it is close.
Let's start with option B: -9. If we cube -9 (-9 * -9 * -9), we get -729. Since -729 is less than 81, we know that -9 is not the correct answer.
Next, let's try option C: 27. If we cube 27 (27 * 27 * 27), we get 19,683. Since 19,683 is greater than 81, we know that 27 is also not the correct answer.
Finally, let's try option D: 9. If we cube 9 (9 * 9 * 9), we get 729. Since 729 is greater than 81, but much closer than the previous two options, we can conclude that 9 is the correct answer.
Therefore, the cube root of 81 is 9. So, the correct answer is D: 9.
