Is the square root a real number?
The square roots of any positive real number are a positive and a negative real number. The square roots of any negative real number are a positive and a negative imaginary number. The square roots of any imaginary number or any complex number are two complex numbers.
Is the square of any real number is positive?
no. Because square of zero is neither positive nor negative.
What are all the real square roots of 400?
The real square roots of 400 are 20 and -20. This is because when you square both of these numbers, you get 400. In general, every positive real number has two square roots: one positive and one negative.
What are the real square roots of 0.0049?
The real square roots of 0.0049 are ±0.07. This is because the square root of a positive number has two real solutions: one positive and one negative. Thus, both 0.07 and -0.07 are the square roots of 0.0049.
What is an example of a real number that is also an irrational?
The square root of any positive, non-square number will be both real and irrational.
When you square a number the number is positive?

Is the square of any real number is positive?
no. Because square of zero is neither positive nor negative.
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 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.
What is the square root of a positive?
The square root of a positive number results in a positive number. For example, the square root of 25 is 5. * * * * * Not true! There are two real square roots for every positive number: one positive and one negative. -5 is as much a square root of 25 as +5 is. However, the positive root is the principal root and so is often presented as the only root.
Why is the square root of a negative number imaginary?
Any real number, when squared will give a positive real number. This is true weather you have a negative real number and square it, or positive. The concept of imaginary numbers was invented to handle equations which needed to use the square root of a negative number, in order to solve them.At first, they were not considered useful beyond this, so they were named imaginary numbers. Through the work of Euler and others, it became evident that imaginary and complex numbers could be useful, especially when analyzing waves, such as electrical waveforms.
