Which complex number has an absolute value of 5?A)–3 + 4i
B)2 + 3i
C)7 – 2i
D)9 + 4i


For this case we can use the Pythagorean theorem to solve the problem.
 We have then for the following complex number:
 Using the Pythagorean theorem:
 Rewriting we have:
A complex number that has an absolute value of 5 is:
A)–3 + 4i

From the answer and question examples above, hopefully, they are able to guide the student deal with the question they had been looking for and take notice of all the stuff declared in the answer above. Then could certainly make some sharing in a group discussion and also learning with the classmate relevant to the topic, so another student also have some enlightenment and still keeps up the school learning.
