$z = \sqrt{40^{2} + 30^{2}}$

Step 1

Raise $40$ to the power of $2$ .

$z = \sqrt{1600 + 30^{2}}$

Step 2

Raise $30$ to the power of $2$ .

$z = \sqrt{1600 + 900}$

Step 3

Add $1600$ and $900$ .

$z = \sqrt{2500}$

Step 4

Rewrite $2500$ as $50^{2}$ .

$z = \sqrt{50^{2}}$

Step 5

Pull terms out from under the radical, assuming positive real numbers.

$z = 50$
