The real part of complex number when z becomes purely real will be
Answers (1)
Given - $z = 2a + i(7 - a)$
For $z$ to be purely real, the imaginary part must be zero. So, we set the imaginary part equal to zero: $7 - a = 0$
Solving for $a$: $a = 7$
Now, substitute $a = 7$ into the real part of the complex number:
Real part of $z = 2a = 2 \times 7 = 14$
Thus, the real part of z when z becomes purely real is $14$
