Answer:
4+9i
Step-by-step explanation:
A number which can be represented or expressed in the form a + bi is said to be a complex number. Here, a and b are the real numbers and i is the solution of an equation ([tex]x^{2} =-1[/tex]).
Moreover, i used in the complex number is called an imaginary number as real number can satisfy the above mentioned equation.
Therefore, the correct answer option is 4+9i.
