Answer:
64,000 (2 s.f)
Step-by-step explanation:
1 km is 1000 metres
so, 1 km² = 1000 x 1000 m²
i.e. 1 km² = 1,000,000 m²
=> 63,800,000,000/1,000,000 = 63,800
The second significant figure is 3 --> 3000
so, to the nearest 1000 we have 64,000 (2 s.f)
Hope it help and if it is correct please give brainliest

Answer:</h2>
option: B is the correct answer.
B. complex numbers.
<h2>
Step-by-step explanation:</h2>
We know that a complex number is always written in the form of :
a+ib
where a and b are real numbers and i is the square root of -1.
i is called an imaginary number.
If a>0 and b>0 then the point lie in the first quadrant.
if a>0 and b<0 then the point lie in the fourth quadrant.
if a<0 and b>0 then the point lie in the second quadrant.
if a<0 and b<0 then the point lie in the third quadrant.
