Find the error (-8x^2y^2)^2= -64x^4y^4

ExtremeBDS [4]

Answer:

$(-8)^2\neq-64$

Step-by-step explanation:

Using the distributive property to expand, we have

$(-8x^2y^2)^2=(-8)^2(x^2)^2(y^2)^2.$

Squaring each term, we have

$(-8x^2y^2)^2=64x^4y^4.$

The mistake was that $8^2=64,$ not $-64.$ Using the fact that $8^2=64,$ the right answer would be

$\boxed{64x^4y^4}$ .

A sphere has a radius of 6 meters. A second sphere has a radius of 3 meters. What is the difference of the volumes of the sphere

Andrew [12]

Since we are dealing with VOLUME, when you increase an amount, we CUBE the difference. 2^3 = 8
The sphere that has 2 times the radius has 8 times the volume.
