1. The problem asks to write the given numbers in standard form, which means expressing them as numerals. 2. Standard form is simply writing the number using digits instead of words. 3. For part (a), "two thousand" means 2 followed by three zeros, so it is written as $2000$. 4. For part (b), "two hundred million" means 2 followed by eight zeros (since a million is $10^6$, two hundred million is $2 \times 10^8$), so it is written as $200000000$. 5. For part (c), "eighty thousand" means 8 followed by four zeros, so it is written as $80000$. Final answers: (a) $2000$ (b) $200000000$ (c) $80000$
