Someone plz help me with this

Phoenix [80]

Answer:

$5y^{6}\sqrt{2}$

Step-by-step explanation:

We want to simplify:

$\sqrt{50y^{12}}$

We rewrite as:

$\sqrt{2\times25 \times (y^{6})^2}$

We split the radical sign to obtain:

$\sqrt{25} \times \sqrt{(y^{6})^2} \times \sqrt{2}$

Simplify the square root for the perfect squares to get:

$5y^{6}\sqrt{2}$

Therefore the simplified form is: $5y^{6}\sqrt{2}$

julsineya [31]

Answer:

volume is 3 1/2 units³

Step-by-step explanation:

The question asks for area, but the answers have dimensions of volume.

The volume is the product of the length, height, and width dimensions:

V = LWH = (2)(1)(1 3/4) = 2 6/4 = 3 1/2 . . . . units³

The volume is 3 1/2 cubic units.
