Beyond the Answer
To factor the expression \( 72 x^{6} y^{5} - 81 x^{6} \), you can start by identifying the greatest common factor (GCF). The GCF here is \( 9 x^{6} \). Factoring this out, you get: \[ 9 x^{6} (8 y^{5} - 9) \] And there you have it! The expression is now factored as \( 9 x^{6} (8 y^{5} - 9) \). Now you can analyze \( 8 y^{5} - 9 \) further, although in this case, it's already in its simplest form unless you want to explore complex roots. Keep practicing factoring!
