sqrt of 20 = 4 and 1/2 or 4.5 (to the nearest tenth)
The square root of 484 is 22. An easy trick to find this out is to round down to the nearest large whole number. In this case, that is 400, the square root of which is 20. If 20 x 20 = 400, what does 21 x 21 equal? Turns out that's 441. Move up to 22 x 22. There you have your answer!
The square root of 400 is 20, as 20 multiplied by 20 equals 400. The square root of 196 is 14, as 14 multiplied by 14 equals 196. Therefore, the expression simplifies to 20 - 14, which equals 6.
The square root of 20 simplified is ±4.5
square root of (6 x 20) = square root of (120) = 10.95
Oh, that's a happy little math question! To simplify this, we can break it down step by step. The square root of 20 is 2 times the square root of 5, and the square root of 40 is 2 times the square root of 10. So, the answer is 4 times the square root of 50. Just remember, there are no mistakes in math, just happy little accidents!
The square root of 2 to the nearest tenth is 1.4

18.3 to the nearest tenth is still 18.3
To find the nearest square unit of a given area, first calculate the square root of the area to determine the side length of the square. Round this side length to the nearest whole number, then square that rounded value to find the nearest square unit. For example, if the area is 20, the square root is approximately 4.47, rounding to 4 gives a nearest square unit of 16 (4²).

It is 2*sqrt(5).
Because the Square Root of negative 1 = i (The imaginary square root of negative 1.) and where if the square root of one number and of another number are multiplied together, the answer is equal to the square root of the two numbers combined. (Square root of 8 times the square root of 5 equals the square root of 40.) So... √(-20) =√20×√(-1) =√4×√5×i =2i(√5) The answer is 2i times the square root of 5. square root (-20) = square root (-1) x square root (20) square root (-20) = i x 4.47213595 square root (-20) = 4.47213595 i
