The least common multiple is 48
Maximum common factor: 12
Least common multiple: 48
If Z satisfies iz = 2 + 3I (I is an imaginary unit), then Z=______ .
Let z = a + bi, (a, B are real numbers), then iz = AI + Bi2 = - B + AI ∵ iz = 2 + 3I ∵ - B + AI = 2 + 3I, we can get a = 3 and B = - 2, so z = 3-2i, so the answer is: 3-2i

If the complex Z satisfies izi = 4, then the maximum value of iz-3i
Let z = 4 (COSA + isina)
Then Z-3 = (4cosa-3) + 4isina
|z-3|²=(4cosa-3)²+16sin²a
=16cos²a-24cosa+9+16sin²a
=25-24cosa
So max = 25-24 × (- 1) = 49
So | Z-3 | max = 7
Using the geometric meaning of complex modulus to find simplicity, that is, number shape combination method
The complex Z represents a circle with a radius of 4 centered on the origin of coordinates. Iz-3i uses the subtraction of complex numbers (similar to vector subtraction, complex numbers actually correspond to vectors) to know the module length of points (3,0) on a circle, that is, the distance between points on a circle and points (3,0). You can see at a glance that it is (- 4,0) on a circle, that is, the maximum value is 7 and the minimum value is 1,
It doesn't take one minute to get the correct answer. This question may be a multiple choice question or a blank question in the college entrance examination. This is the winning way to get high scores in the college entrance examination

Find the complex number Z (1) iz (Z has a transverse) + 2Z = 3I; (2) 2Z + | Z | (Z has a transverse) = - 1 + 8i
Let z = a + bi, then its conjugate complex Z '= a-bi (1), iz' + 2Z = 3I, I * (a-bi) + 2 (a + bi) = 3I is reduced to 2A + B + (a + 2b-3) I = 0, then 2A + B = 0, and a + 2b-3 = 0, the solution is a = - 1, B = 2, so z = - 1 + 2I (2), 2Z + ｜ Z '= - 1 + 8i, that is, 2 (a + bi) + a-bi = - 1 + 8i, that is, 2A + radical [a ^ 2 + B ^ 2] + 2bi =
