Is the square root of any real number always positive?
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
When you square a negative number is it positive or negative?
The square of a real number is always positive no matter which real number you start with. Therefore, a negative number squared is positive. For example: 2 * 2 = 4, -2 * -2 = 4.
What is the Square root of 160?
Negative numbers do not have square roots. Multiplying any number by itself will always be a positive number. For example, -1 x -1 is 1. Because two negatives cancel themselves out, and regular numbers are always positive.
If a negative number squared is positive why isn't the square root of a positive number negative?
When a negative number is squared, the negative sign is essentially squared along with the number, resulting in a positive value. However, when taking the square root of a positive number, we are looking for the value that, when squared, gives us the original positive number. Since both a positive and negative number can square to the same positive value, the convention is to consider the principal (positive) square root by default. The negative square root is also a valid solution in many contexts, but for simplicity and consistency, the positive square root is typically chosen.
Why does every positive number have two square roots?
Square root of 25 is 5 or -5. 5 X 5 is 25 -5 X -5 is also 25 A negative number multiplied by a negative number is always positive.
Why is any number raised to a even power positive?

Is the square root of any real number always positive?
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
When can the square of a negative number be negative?

When squaring a negative number if the factor is a negative and the exponent is positive will your answer be negative or positive?
If you square any real number it will always be positive.
Why is the last term of a perfect square trinomial always positive?

Are the square roots of all positive integers irrational If not give an example of the square root of a number that is a rational number?
The square root of any positive square number is always rational as for example the square root of 36 is 6 which is a rational number.
When you square a negative number is it positive or negative?
The square of a real number is always positive no matter which real number you start with. Therefore, a negative number squared is positive. For example: 2 * 2 = 4, -2 * -2 = 4.
How do you square negative numbers?
Multiply the number by its self and the answer will always be positive (negative times a negative is positive)
The square of a positive integer?
The square of a positive number is positive. By the way, the square of a negative number is also positive.
How do you find whether the square of any nonzero number is sometimes always or never a positive number?
Remember that when two numbers with the same sign are multiplied,their product is always positive.
