## Homework Statement

Show that if T is normal, then T and T* have the same kernel and the same image.

## Homework Equations

N/A

## The Attempt at a Solution

At first I tried proving that Ker T ⊆ Ker T* and Ker T* ⊆ Ker, thus proving Ker T = Ker T* and doing the same thing with I am T, but could not find a way of doing so. I am relatively certain this has to do with discomposing T into direct sum subspace or doing something with the orthonormal basis of V comprised of eigenvalues of T but I cannot seem to figure it out.

I would love some assistance on the matter.
