Answer:

[tex]\sqrt{4}[/tex][tex]\sqrt{z^2}[/tex][tex]\sqrt{z^2}[/tex][tex]\sqrt{z^2}[/tex]

Step-by-step explanation:

[tex]\sqrt{56z^7}[/tex] = [tex]\sqrt{4}[/tex][tex]\sqrt{14}[/tex][tex]\sqrt{z^2}[/tex][tex]\sqrt{z^2}[/tex][tex]\sqrt{z^2}[/tex][tex]\sqrt{z}[/tex]

the perfect squares are:

[tex]\sqrt{4}[/tex][tex]\sqrt{z^2}[/tex][tex]\sqrt{z^2}[/tex][tex]\sqrt{z^2}[/tex] = 2z³
