Step-by-step explanation:
√(m + n) = √m + √n
Square both sides:
m + n = m + 2√(mn) + n
Simplify:
0 = 2√(mn)
mn = 0
The equation is only true if either m or n (or both) is 0.
We can write the question as this equation :
Where x is the distance in kilometers, so to find x:
X= 6.7*3*10^5 = 20.1*10^5 km
