if x is equal to the square root of 81 then x is ±9 (plus or minus 9)
Square root of 49 = 7... Square root of 9 = 3... 3 x 7 = 21
sqrt(4) = 2 sqrt(9) = 3 Therefore, the square root of 4 plus the square root of 9 is equal to 2 + 3 = 5.
To find the square root of a number you must find the number that can multiplied by itself to equal that number Ex: the square root of 9 is 3 because 3*3=9
No - a square root of a negative number is an imaginary number. for example, sqrt(-9) is equal to 3i.
√39=~6.2449979983983982058468931209398 √81=9
if x is equal to the square root of 81 then x is ±9 (plus or minus 9)
Square root of 49 = 7... Square root of 9 = 3... 3 x 7 = 21
-3 squared = 9. The square root of -9 is 3i, i being the square root of -1
No, the square root of 9 is 3. Neither of them are equal.
9
Treat it like a positive and add an i. Explanation: The square root of negative nine is equal to the square root of nine times negative one is equal to the square root of nine times the square root of negative one. The square root of negative one represented by an italic lower case i. The square root of negative nine is 3i. √-9 = √9 * -1 = √9 * √-1 = 3i
sqrt(4) = 2 sqrt(9) = 3 Therefore, the square root of 4 plus the square root of 9 is equal to 2 + 3 = 5.

Taking the square root means to find a number that, when squared (when multiplied by itself) is equal to the given number. If I ask for the square root of 9, I want a number that, when multiplied by itself, is equal to 9 - in this case, the answer is 3.
No - a square root of a negative number is an imaginary number. for example, sqrt(-9) is equal to 3i.
