Answer:
hey mate here is your answer...
Step-by-step explanation:
Given,
z=(2−3i)
z
2
−4z+13
=(2−3i)
2
−4(2−3i)+13
=−5−12i−8+12i+13
=−12i+12i−5−8+13
=0
4z
3
−3z
2
+2z+170
=4(2−3i)
3
−3(2−3i)
2
+2(2−3i)+170
=4(−46−9i)−3(−5−12i)+2(2−3i)+170=4(−46−9i)−3(−5−12i)+2(2−3i)+170
=−184−36i−3(−5−12i)+2(2−3i)+170
=−184−36i+15+36i+4−6i+170
=5−6i
