1) x^8  y^8
2) 9x^4  16y^8
3) 8x^6  27
4) 4x^2/9  y^4

Best ResponseYou've already chosen the best response.01.) x^8  y^8 = (x4 + y4) • (x4  y4)  squares 2.) \[3^2x^4  2^4y^8\]  squares 3.) 8x^627  cubes 4.) I'm not sure on this one. Is 2/9 a fraction or is it dividing the term 4x^2 by 9? If I had to guess, it would be squares.

Best ResponseYou've already chosen the best response.11) can be factored more the expression (x^4x^4) is also a difference of squares 2) seems a bit off but yes use difference of squares 3) agreed used difference of cubes 4) use difference of squares

Best ResponseYou've already chosen the best response.1\[u^2v^2=(uv)(u+v) \text{ is how to factored difference of squares } \\ u^3+v^3=(u+v)(u^2uv+v^2) \text{ is how to factored sum of cubes } \\ u^3v^3=(uv)(u^2+uv+v^2) \text{ is how to factored difference of cubes }\]

Best ResponseYou've already chosen the best response.1\[\frac{a^2}{b^2}x^2v^2 \\ \text{ where } v=u^2 \\ \text{ first all notice this can be written as } \\ (\frac{a}{b}x)^2v^2 \\ \text{ this is a difference of squares }\]

Best ResponseYou've already chosen the best response.1example: \[\frac{16}{25}x^2u^4 \\ \frac{4^2}{5^2}x^2(u^2)^2 \\ (\frac{4}{5}x)^2(u^2)^2 \\ (\frac{4}{5}xu^2)(\frac{4}{5}x+u^2)\]

Best ResponseYou've already chosen the best response.1\[\frac{4}{9}x^2y^4 \\ \frac{2^2}{3^2}x^2(y^2)^2 \\ (\frac{2}{3}x)^2(y^2)^2 \] can you try the factoring part?
