What is the modulus of |9+40i|?

Talja [164]

Answer:

Step-by-step explanation:

We know that complex numbers are a combination of real and imaginary numbers

Real part is x and imaginary part y is multiplied by i, square root of -1

Modulus of x+iy = $\sqrt{x^2+y^2}$

Here instead of x and y are given 9 and 40

i.e. 9+40i

Hence to find modulus we square the coefficients add them and then find square root

|9+49i| = $\sqrt{9^2+40^2} =\sqrt{1681}$

By long division method we find that

|9+40i| =41
