To type exponents easily on a Chromebook, you can use the caret symbol (^) followed by the exponent (e.g., 2^3 for 2 to the power of 3) in plain text. For formatted text (like in Google Docs), highlight the exponent number, then press Ctrl + . (period) to superscript it. Alternatively, go to Format > Text > Superscript from the menu. For frequent use, you can also enable the Unicode input (e.g., typing ² using Ctrl + Shift + U, then 00B2, and press Enter).
