The square root of any positive real number (as in this case) is a real number. (Such square roots are usually irrational.)The square root of a negative real number, such as the square root of -15, is an imaginary, and therefore also a complex, number.

A complex number for example. Complex numbers involve i, the imaginary square root of -1.

Complex numbers are numbers of the a + bi where a and b are real number and i is the imaginary square root of -1.

The square root of 100 is rational since it is not repeating.

I am not sure what you want to calculate; anyway, the square root of a negative number is a complex number: in this case, "i" multiplied by the square root of 7. The remaining calculations will also result in complex numbers. When you calculate points, you usually want a real number, not a complex number.

No. An irrational number is still a real number - it lives on the number line.The square root of -1 (known as i) is an imaginary number. It is on the imaginary axis of the complex plane.A number with components from the real axis and the imaginary axis is a complex number, and is on the complex plane.

A number of the form a+bi where a and b are real numbers and i is the square root of -1.

yes, you can find a real root to the cube root of any negative real number. There will also be two complex roots which satisfy it, as well.

Complex numbers are numbers of the a + bi where a and b are real number and i is the imaginary square root of -1.

No you can not. Complex roots appear as conjugates. if a root is complex so is its conjugate. so either the roots are real or are both coplex.

The square root of 100 is rational since it is not repeating.

There is no real number whose square root can be negative so there is no real solution. So mathematicians invented the imaginary number i with the property that i*i = -1 i is fundamental to complex numbers.

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.

In the context of algebra, the term real root refers to the solution to an equation which consists of a real number rather than an imaginary or complex number (a complex number being a combination of real and imaginary numbers). You may recall that any given equation will have the same number of roots (or solutions) as the highest exponent in the equation, so that if you are dealing with x squared, you have two roots. Often there would be one real root and one imaginary root. In general, the real roots are more useful, although there are some circumstances in which imaginary or complex roots are also relevant to what you are doingl.

The square root of negative 36 is an imaginary number and therefore not an irrational number. For a number to be irrational it must first be real.
