### What is the square root of 261?

The square root of 261 can be written as the square root of
(9x29). Now the product rule for square roots tells us this is the
same as square root of 9 multiplied by the square root of 29. This
is 3xsquare root of 29. The square root of 29 can only be
approximated.
One approximation to square root of 261 is 16.1555.

### Can the square root of x be added to the square root of 3x?

No. The Square root of x is not the value of x. So it can not be
simplified beyond:
Root X + root 3x
Yes.
The square root of 3x equals the square root of 3 times the
square root of x, so when you add another square root of x, you can
factor out the square root of x, thereby simplifying the expression
to the square root of x times the sum of one plus the square root
of three.

### What is the square root of a negative number plus the square root of a negative number?

Nothing. You cannot have a square root of a negative number. The
square root of negative one is called i, but i is an imaginary
number. It does not exist and does not follow the properties of
real numbers. (For example, if a and b are positive, then the
square root of a times the square root of b is the square root of
ab. But the square root of -7 is not the square root of 7 times
i.)

### What is the nonnegative square root of a number?

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.

### How do you do square roots with negatives?

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
