No. It is an imaginary (or complex) number.

No. The sum of an irrational number and any other [real] number is irrational.
A negative irrational number can be thought of as an irrational number multiplied by -1, or an irrational number with a minus sign in front of it.
- 2 - 3i
If an irrational number is added to, (or multiplied by) a rational number, the result will always be an irrational number.
rational number means 3/5 and ....irrational number means imaginary part will be added eg:3i/5
The "i" in 3i means the number is imaginary.

3i where i is the square root of negative one.3i x 3i = -9
The complex conjugate of a number in the form a + bi is simply the same number with the sign of the imaginary part changed. In this case, the number is 7 + 3i, so its complex conjugate would be 7 - 3i. This is because the complex conjugate reflects the number across the real axis on the complex plane.
[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]
An irrational number.
The conjugate of (84-3i) is (84+3i). This gives you a real number when multiplied.
No. The sum of an irrational number and any other [real] number is irrational.
The sum of a rational and irrational number must be an irrational number.
rational * irrational = irrational.
No, 3.56 is not an irrational number. 3.56 is rational.
