Question
Find the distance
d=52
Alternative Form
d≈7.071068
Calculate
i,7
Rewrite the complex number in standard form
0+i,7
Any real number can be written as a complex number with the imaginary part 0
0+i,7+0×i
The complex number for a+bi can be represented as an ordered pair (a,b)
(0,1),(7,0)
The distance between the points (a,b) and (s,t) in the complex plane is d=(s−a)2+(t−b)2
d=(0−7)2+(1−0)2
Solution

Calculate
(0−7)2+(1−0)2
Removing 0 doesn't change the value,so remove it from the expression
(−7)2+(1−0)2
Removing 0 doesn't change the value,so remove it from the expression
