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 20 simplified is ±4.5
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.
square root of (6 x 20) = square root of (120) = 10.95

18.3 to the nearest tenth is still 18.3
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
The square root of 75 is 8.66 and the square root of 20 is 4.47.
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.
