Saya sedang belajar Bahasa Indonesia

[I am studying the Indonesian language, for those of you who don't speak Indonesian.]

In 1972, President Suharto announced certain orthographical changes to the language. One of these was to proscribe usage such as hati². Now in Bahasa, which doesn't have plurals as English speakers know them, doubling the word is use to indicate a plural, a comparative, or to add emphasis. So hati-hati would mean "be very careful!", and could be written hati-squared.

I rather like the use of exponents to add emphasis - and would be tempted, before 1972, to use higher powers. Hati³ in especially dangerous situations, for example.
