Best ResponseYou've already chosen the best response.3Let there be Z (a complex number ) = a + ib So , we have to find the modulus of Z = Z = a+ib It is given by Z = \(\sqrt{x^2+y^2}\)

Best ResponseYou've already chosen the best response.3so let us take the question itself as an example : 78i = \(\sqrt{7^2+8^2}\)= \(\sqrt{49 + 64} = \sqrt{113}\)
