Every positive integer has two square roots, a positive square root and a negative square root. This is because, just like a positive number multiplied by a positive number is equal to a positive number, a negative number multiplied by a negative number is equal to a positive number. Therefore, rounded to two decimal places, the positive square root is equal to 7.28, and the negative square root is -7.28.
Positive or negative 4i
Any positive number has two square roots, a positive square root and a negative square root. In this instance, the square root of 4900 is equal to ±70 (that is, 70 and –70).
Positive or negative (√8 * i) = Positive or negative 2.828i
+6 is the positive square root of 36.

Definition of Square Root: The Square Root of a number 'X' is equal to 'A' when X=A*A By definition, the square root of a positive number has two answers, one negative and one positive, that have equal magnitudes. i.e. The square roots of 4 are 2 and -2. The Non-Negative Square Root is simply asking for the positive root.

Positive or negative (√8 * i) = Positive or negative 2.828i
The positive square root of 64 is exactly equal to 8.
Such that, rounded to two decimal places, the square root of 62 is equal to 7.87, the square root of -62 is equal to 7.87 i. ============================================================= You cannot have a square root for a negative number as the multiplication of any number with itself will ALWAYS give a positive number
The square root of a real number is not always positive. The square root of any positive number is positive, the square root of zero is zero (not positive), and the square root of a negative number is complex (i.e. neither positive nor negative). The square root of 16 = -4 or 4. The square root of 0 = 0 The square root of -16 = -4i or 4i
+6 is the positive square root of 36.
The positive square root of 289 is 17.
I think it is Xi (whatever the square root of the positive is times i). i is an imaginary number that when you square it, it becomes negative. eg. the square root of -4 is 2i. Without "i", it would be impossible to square root a negative number, as any number times itself will always equal a positive.
The product of two negative numbers is a positive number. Ergo, the product of the square of a number is equal to the square of its negative equivalent.
