Question

Prove,

$\sqrt{-2+2i√3}$ + $\sqrt{-2-2i√3}$ = $2$​

Answer 1

Step-by-step explanation:

√(-2+2i√3)+√(-2-2i√3)

let a=√(-2+2i√3)

b=√(-2-2i√3)

a²=-2+2i√3;

b²=-2-2i√3;

ab=√(4-4i²3)=√(4+12)=4

(a+b)²=a²+b²+2ab;

a+b=√(a²+b²+2ab)

a+b=√(-2+2i√3-2-2i√3+2.4)

=√(-4+8)

=√4=2

Answer 2

Answer:

Lions generally like to live in large groups, and these are known as ‘prides’. In the pride there will be one male lion who is the head of the tribe, along with several other males and females. It is the female lion who hunts for food in the savannah. The females bring their prey back to the pride, and therefore, the male lions rely on the females for their meals
