Step-by-step explanation:

$\sqrt{56z^7}\\ \sqrt{4*14*z^6*z}\\2 z^3\sqrt{14z}$

Answer 2

Answer:

$\sqrt{4}$$\sqrt{z^2}$$\sqrt{z^2}$$\sqrt{z^2}$

Step-by-step explanation:

$\sqrt{56z^7}$ = $\sqrt{4}$$\sqrt{14}$$\sqrt{z^2}$$\sqrt{z^2}$$\sqrt{z^2}$$\sqrt{z}$

the perfect squares are:

$\sqrt{4}$$\sqrt{z^2}$$\sqrt{z^2}$$\sqrt{z^2}$ = 2z³
