Sarah's class is squaring complex numbers. Sarah says that (3+4i)^2 = (9+16i^2)=(9-16)=-7. Did Sarah square (3+4i) correctly? If not explain her mistake and provide the correct answer.

substitute,

circle 1 = 5

circle 2 = 20

circle 3 = 44

in this case no matter how you add, you will always get a perfect square..

hence proved

happy to

pls mark as brainliest

t= half of the arc subtended by t.

r= half of the arc subtended by r.  

t+r= half of the arc subtended by t + half of the arc subtended by r= half of 360=180
