3ay(a + 2y)^2
=3ay(a + 2y)(a + 2y)
=3ay (a^2 + 2ay + 2ay + 4y^2)
= 3ay (a^2 + 4ay + 4y^2)
= 3a^3y + 12a^2y^2 + 4y^3 a)

This rational expression is nonequivalent. 5x / 25x^4 ; x^3 / 5x^15 True or false?????

FromTheMoon [43]

It is nonequivalent. Figure it out this way. Think about what number has to be multiplied by both the numerator and the denominator of $\frac{5x}{25x^4}$ to get to $\frac{x^3}{5x^15}$ . It has to be the samee number for the one expression to be equivalent to the other. To get from 5x to x^3, we have to multiply by 1/5x^2. When we do that we get x^3. Good. Now we have to multiply the denominator by the same thing, 1/5x^2. $25x^4(\frac{1}{5}x^2)=5x^6$ . As you can see, they are not equivalent.
