# Modulus

Algebra Level 3

In the complex plane ,the horizontal axis is called the real axis and the vertical axis is called the imaginary axis. The complex number $$a$$+ $$bi$$ graphed in the complex plane is comparable to the point $$(a,b)$$ graphed in the standard $$(x,y)$$ coordinate plane. The modulus of the complex number $$a$$+ $$bi$$ is given by $$\sqrt{a^{2} + b^{2}}$$. Which of the given complex numbers $$z_{1}$$,$$z_{2}$$,$$z_{3}$$,$$z_{4}$$ and $$z_{5}$$ has the greatest modulus?
