Find the square root of 81: √81 .(1 point)
The square root of 81 is 9.
To find the square root of 81 (√81), you can follow these steps:
1. Start by finding the prime factors of 81. Since 81 is a perfect square, it can be written as 3^4.
2. Take the square root of each factor. The square root of 3^4 is 3^2, which simplifies to 9.
Therefore, the square root of 81 (√81) is 9.
To find the square root of 81 (represented by √81), you can follow these steps:
1. Start by determining the factors of the number 81.
- The factors of 81 are 1, 3, 9, 27, and 81 itself.
2. Next, find pairs of factors where one factor multiplied by itself equals 81.
- The pair of factors that satisfy this condition is 9 and 9 because 9 * 9 = 81.
3. Finally, take the square root of the number, which is the factor that satisfies the condition in step 2.
- The square root of 81 is 9, so √81 = 9.
Therefore, the square root of 81 is 9.
