If `z` is a complex number, then a. `|z|^2>|z^2|` b. `|z|^2=|z^2|` c. `|z|^2<|z^2|` d. `|z|^2geq|z^2|`

Explanation

Given: `z` is a complex number.

Now.

Let `z=x+i y`

then `|z|^{2}=(|x+i y|)^{2}`

`Rightarrow|z|^{2}=(.sqrt{x^{2}+y^{2}}|^{2}`.

`Rightarrow|z|^{2}=x^{2}+y^{2}-(2)`

Now,

`|z^{2}| =|(x+i y)^{2}|`
