2700000
Explanation:
Here's a handy shortcut for doing problems with lots of extra zeroes in your head:
- Count how many zeroes each number has on the end, then add them together. 300 has 2 zeroes, 9000 has 3. Add them to get 5. Save this for later.
- Multiply the numbers together WITHOUT the zeroes. Removing zeroes, we now have the numbers 3 and 9.
#3*9=27# . - Add the zeroes on the end. 2700000
