Verb[て] + みせる

This pattern expresses strong resolve or determination by showing the listener that you will do something for sure. It emphasizes the speaker’s commitment and intention to prove, demonstrate, or convince others through action. It is often used when you want to reassure someone or assert that you will achieve or complete something, sometimes in the face of doubt. The verb preceding て is in its て-form and is followed directly by みせる, which adds the nuance of “showing you” what you can do. The form can be used in present/future and, with different tenses, to convey commitment in a range of situations (e.g., promising to prove something, or insisting that you will carry out an action). Typical contexts include personal challenges, demonstrations of capability, or responses to skepticism.
