Using a calculator, the square root of 22 is found to be 4.69041576. However, you can find an approximation without using a calculator: √ 22 = √ (44/2) = √ ((4*11)/2) = 2√ (11/2) = 2 √ 5.5 If you happen to know the square root of both five and six, than you can estimate the square root of 5.5. Alternatively, you could Find the square root of 11 and divide it by the square root of 2. The first method is probably easier. I would estimate the √ 5.5 at about 2.34, which when multiplied by 2 would equal 4.68, which is pretty close to the calculator answer.
2 square root 2
the square root of 4 is 2 square root 2
The square of any square root is equal to the number itself. For example, the square of the square root of 2 squared is equal to 2. The square root of 10 squared is equal to 10.Similarly, the square of the square root of 2 is equal to 2.
square root of 20 = square root of 4 * square root of 5. square root of 4 = 2, so your answer is 2 square root of 5.

The square root of the square root of 2
No, the square root of 8 has to be between 2 and 3, closer to 3.
2 square root 2
square root 2 times square root 3 times square root 8
The square root of 2 plus the square root of 2 is equal to twice the square root of 2, therefore the correct answer is: 2(√2) or √8
4
the square root of 4 is 2 square root 2
2 is the same as the square root of 4. Square root of 4 multiplied by square root of 2 is equal to the square root of 8.
