How to find absolute value of a squareroot? Like what is absolute value of radical 10. The problem I have is -2+i sqrt 10. What is absolute value of this complex number?
The absolute value of complex number a + bi is given by sqrt(a^2 + b^2)
So with z = -2 + i*sqrt(10) we would have abs(z) = sqrt(4 + 10). Or abs(z) = sqrt(14)
.
