If, and only if the positive value is > the negative value.

Every positive number has two square roots. Their absolute values are the same. One is positive and the other is negative.

It depends on what the value of x is. If x is a positive number, then it will be negative because a negative number multiplied by a positive number is negative. If x is a negative number, then it will be positive because the product of two negative numbers is always a positive number.

Positive plus positive is positive. Negative plus negative is negative. Positive plus negative is positive if the absolute value of the positive number is greater than the absolute value of the negative one. Positive plus negative is negative if the absolute value of the negative number is greater than the absolute value of the positive one.

The absolute value is only ever positive. * * * * * Or 0.

The square of negative iota will be the same as the square of positive iota (i.e. -1) because when a negative number is multiplied by a negative number, the answer is positive.

Negative, because 5 is an odd number

√(a^2) That is |a| (the absolute value of a) Because if a is positive, a^2 is positive, and since √ is a positive square root, √(a^2) is a. If a is negative, a^2 is positive, and since √ is a positive square root, √(a^2) is -a. So if a is positive, √(a^2) is positive (which is a) If a is negative, √(a^2) is also positive (which is -a) So √(a^2) is |a| for every a.

There must be some value otherwise nobody would do them. On that basis, the value must be positive.

No, the product of the multiplication of a positive and a negative value is negative.

No it is not true. The absolute value of a number is simply the value of the number with a positive sign.

No. There is no real number which multiplied by itself forms a negative number.A negative times a negative is a positive, and only a positive times a negative is a negative.However, in calculus there is an "imaginary value" (called i ) which represents the square root of -1.Square roots of larger negative numbers are represented by the square of the absolute value times i .

If, and only if the positive value is > the negative value.

Every positive number has two square roots. Their absolute values are the same. One is positive and the other is negative.

If the absolute value of the negative is bigger than that of the positive, then the answer is negative. If the absolute value of the negative is the same, then zero. If the absolute value of the negative is smaller, then positive. Absolute value is the value ignoring the sign.

It is - as well as positive 3. Multiplying a negative number by another negative always results in a positive value. Therefore the square root of 9 can be either 3 or -3.

Negative 10 because the absolute value of a number is the positive and negative form of that number. For example: The absolute value of 9 is positive 9 and negative 9. Therefore, it would be greater than the absolute value of any number below it.
