Yes, all real numbers are complex numbers.
NO!!!!
It is a negative number.
The conjugate is 7 - 3i is 7 + 3i.
The conjugate is 7-5i
They are 7 ± 11i
Yes. And since Real numbers are a subset of complex numbers, a complex number can also be a pure real.Another AnswerYes, for example: (0 + j5) is a complex number, whose 'real' number is zero.
[7 - 3i] To find the conjugate: the sign of the real part stays the same, and the sign of the imaginary part is reversed. So the conjugate of [7 + 3i] is [7 - 3i]
The conjugate is 7 - 3i is 7 + 3i.
The conjugate is 7-5i
31
To get the conjugate simply reverse the sign of the complex part. Thus conj of 7-4i is 7+4i
They are 7 ± 11i
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.
Adjoint operator of a complex number?
The absolute value of a complex number is the magnitude of the number, which is found from sqrt(a² + b²) for the complex number a + bi
Yes. And since Real numbers are a subset of complex numbers, a complex number can also be a pure real.Another AnswerYes, for example: (0 + j5) is a complex number, whose 'real' number is zero.
You get a complex number unless the real number happens to be 0 or 1.
Graphically, the conjugate of a complex number is its reflection on the real axis.
No. A complex number is a number that has both a real part and an imaginary part. Technically, a pure imaginary number ... which has no real part ... is not a complex number.
