標題:
It is given that z=(3m+2)+(m-4)i, where m is real number and i^2=-1.If z is a real number, find the value of m.?
最佳解答:
If z is a real number Let's (m-4)i=0i m=4
其他解答:
z = (3m + 2) + (m - 4)i If z is a real number, the imaginary part of z should be zero, i.e. (m - 4)i = 0 m - 4 = 0 m = 4|||||how about this part(3m + 2)
