Multiply the complex numbers: (1∕2 + 4i)2 Question 10 options:

A)

–153∕4 + 4i

B)

153∕4 + 8i

C)

–153∕4 + 8i

D)

153∕4 + 4i

[I'm supposing that you have to find the value of (1/ 2 + 4i)²]

Step-by-step explanation:

we must know that

[I'm also assuming that instead of -153/4 + 4i option A says -63/ 4 + 4i.]

so the answer is option A.

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3

3 3 6, because in every triangle the longer side is always shorter than the sum of the other two
