Answer:

Question 1.    [tex]y=5[/tex]

Question 2.   [tex]y=4[/tex]

Step-by-step explanation:

1.         [tex]y^{3} =125[/tex]

Take the cube root of both sides:

[tex]{y}=\sqrt[3]{125} \\[/tex]

or

[tex]y=125^{\frac{1}{3} }[/tex]

[tex]y=5[/tex]

2.        [tex]y^{2}+4=20\\[/tex]

Subtract 4 from both sides.

Then you have:

[tex]y^{2} =16[/tex]

Take the square root of both sides:

[tex]y=\sqrt{16}[/tex]

[tex]y=4[/tex]
