What is the difference between a muscular strength exercise and a muscular endurance exercise?

Muscular strength exercises build neuropathways to your brain, strengthening and building your muscle. Muscular endurance exercises work the muscle you already have. For example, weight lifting would be muscular strength because you're building muscle. Running would be muscular endurance because you're seeing how long those leg muscles can last. However, the two can also "intermix" and you usually do both at the same time.
