Question

Which choice is equivalent to the expression below when y is greater or less than 0?

Answer 1

Answer to your questionis A. y sqrt y

explanation - right on test

Answer 2

A. y√y

Step-by-step explanation

The given expression is:

`\sqrt{ {y}^(3) } + \sqrt{16 {y}^(3) } - 4y √(y)`

We factor the perfect square in the first two terms to obtain;

`\sqrt{ {y}^(2) * y} + \sqrt{ {(4y)}^(2) * y } - 4y √(y)`

This simplifies to:

`y√(y ) + 4y √(y ) - 4y √(y)`

We simplify to get;

`y√(y ) + 0 = y √(y)`

The correct choice is A.
