Enter an exact number: \( 8 r^{4} s^{4}-3 r^{4} s^{5} \)

The expression you've provided is: \[ 8r^{4}s^{4} - 3r^{4}s^{5} \] To determine an exact number from this expression, specific values for the variables \( r \) and \( s \) are required. Without assigning particular numbers to \( r \) and \( s \), the expression remains algebraic and cannot be simplified to a single numerical value. **However, if you wish to simplify the expression by factoring, here's how you can do it:** 1. **Identify the Greatest Common Factor (GCF):** - Both terms share \( r^{4}s^{4} \) as a common factor. 2. **Factor out the GCF:** \[ 8r^{4}s^{4} - 3r^{4}s^{5} = r^{4}s^{4}(8 - 3s) \] So, the factored form of the expression is: \[ r^{4}s^{4}(8 - 3s) \] **If you provide specific values for \( r \) and \( s \), I can help you compute the exact numerical value of the expression.**
