4.4721359549995793928183473374626 and -4.4721359549995793928183473374626 The cube root of 400 is also equal to the square root of 20. (IIRC) Another way to approach it: √(20)=√(4x5) =2√(5)
The square root of 20 is approximately 4.47, and the square root of 40 is approximately 6.32. When you multiply these two values together, you get approximately 28.3. This is because the square root of a product is equal to the product of the square roots of the individual numbers.
The square root of 15 times the square root of 5 can be simplified as the square root of (15 * 5), which equals the square root of 75. The square root of 75 can be further simplified as 5 times the square root of 3. Therefore, the square root of 15 times the square root of 5 is equivalent to 5 times the square root of 3.
Square root of 5 = ± 2.236068Square root of 11 = ± 3.316625
20 is 5x4 so we can simplify it like this: ____ ______ / = / \/ 20 \/ 5 x 4 Also note that: ____ / = 2 \/ 4 So... ____ ____ / = / \/ 20 2 \/ 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
It is 2*sqrt(5).
