The magnitude of a complex number a+bi denoted by {z} is the square root of a squared + b squared. Example: the magnitude of 2-3i is the sqare root of 13.

talking of complex plane the magnitude of a complex number is the distance of a complex number from the origin
where x+iy represents a complex number with cordinates (x,y)
now apply the distance formula and get the result
in this case it is sqrt(9+49) = sqrt(58)

magnitude of complex no
a+-bi
=sqrt[a^2+b^2]
magnitude of 3-7i
=sqrt[3^2+7^2]
=sqrt[9+49]
=sqrt58

Use pythagoras theorem.
(3^2+7^2)^(1/2) = 58^(1/2) ~ 7.62
