Simplify square root of 3i
Problem
Solution
Express the complex number in polar form. The number
3*i has a magnituder=3 and an angleθ=π/2
Apply the square root property for complex numbers in polar form, which is
√(,r*e^(i*θ))=√(,r)*e^(iθ/2)
Convert the result back to rectangular form using Euler's formula
e^(i*x)=cos(x)+i*sin(x)
Substitute the known values for
cos(π/4)=√(,2)/2 andsin(π/4)=√(,2)/2
Distribute the
√(,3) to find the final simplified expression.
