Final answer:
First four terms of the sequence an = nn are 1, 4, 27, and 256 respectively. The 100th term is 100100, which is an exceedingly large number and requires electronic computation.
Step-by-step explanation:
To find the first four terms and the 100th term of the sequence where the nth term is given by an = nn, we substitute n with the position of the term we want to find. For the first four terms, we have:
To find the 100th term, a100, we calculate 100100. This is an extremely large number and is normally computed using a calculator or computer.
