Question

Can someone help me solve these pls?

Answer 1

y=4 4 times 4 is 16 and 16 plus 4 is 20

Answer 2

Question 1.
`y=5`

Question 2.
`y=4`

Explanation:

1.
`y^(3) =125`

Take the cube root of both sides:

`{y}=\sqrt[3]{125} \\`

or

`y=125^{(1)/(3) }`

`y=5`

2.
`y^(2)+4=20\\`

Subtract 4 from both sides.

Then you have:

`y^(2) =16`

Take the square root of both sides:

`y=√(16)`

`y=4`
