Transcript text: Evaluate the expression for $\mathrm{z}=-3.2$. \[ z^{2} \] \[ z^{2}= \]

Solution

Step 1: Substitute the value of $ z $

Substitute $ z = -3.2 $ into the expression $ z^{2} $: \[ z^{2} = (-3.2)^{2} \]

Step 2: Calculate the square

Calculate the square of $-3.2$: \[ (-3.2)^{2} = (-3.2) \times (-3.2) \]

Step 3: Perform the multiplication

Multiply $-3.2$ by $-3.2$: \[ (-3.2) \times (-3.2) = 10.24 \]
