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

Q: How do you do square roots with negatives?

Write your answer...

The square roots of 9 are +3 and -3. The integers of their negatives are -3 and +3 respectively.

Any positive number has two square roots, a positive square root and its negative equivalent. This is because two negatives multiplied together equal a positive. In this instance, sqrt(625) = Â±25 (that is, 25 and -25).

They can, but they are called imaginary numbers. This is because a "square" of something is the number that, when multiplied by itself, will equal the first number. A negative multiplied by a negative equals a positive, and positives can't turn into negatives on their own, so there are no square roots of negative numbers.

(-5)^2 = (-5)(-5) = 25 The negatives cancel one another out.

The square roots are -1.07 and +1.07The square roots are -1.07 and +1.07The square roots are -1.07 and +1.07The square roots are -1.07 and +1.07

The square roots of 529 are: ± 23.

square inches do not have square roots only number have square roots.

Perfect square roots are square roots that have a whole number that can go into it perfectly. Nonperfect square roots are square roots that have decimal numbers going into it. Example: Perfect Square Root: 144- Square Root: 12 Nonperfect Square Root: 24- Square Root: About 4.89

No. The square roots 8 are irrational, as are the square roots of most even numbers.

You call them principal square roots.

The square roots of 64 are +8 and -8.

The square roots of 8100 are 90, -90

The answer depends on "different from WHAT?" Positive cube roots, or negative square roots?

There are no real square roots of -256. But using complex numbers the square roots of -256 are 16i and -16i.

A number multiplied by itself is the square of that number. The reverse procedure is the square root. You can get help for square roots from you teacher, a tutor, a student who understands square roots, etc.

The square roots of 25 are 5 and -5

The two square roots of 36 are 6 and -6.

256 has two square roots: 16 and -16.

You just figure out the square roots and than subtract them...

The square roots of 196 are 14 and -14.

The square roots of 114 are approx 10.6771 and -10.6771

There is no number that has more than two square roots.By definition, the "square" bit implies two.Every number has exactly:TWO square roots,THREE cube roots,FOUR quadratic roots,etc.

No. Lots of square roots are not rational. Only the square roots of perfect square numbers are rational. So for example, the square root of 2 is not rational and the square root of 4 is rational.

0.64 has square roots {0.8, -0.8}.

The two square roots of 18 are: 4.242641 and -4.242641
