Order 3.21 x 10, 42 x 10^4, and 0.11 x 10^10 from least to greatest
To order the given numbers from least to greatest, we need to compare their magnitudes by looking at the exponents of 10.
First, let's rewrite the numbers using standard decimal notation:
3.21 x 10 = 3.21
42 x 10^4 = 420,000
0.11 x 10^10 = 1,100,000,000
Now we can easily order these numbers from least to greatest:
3.21, 420,000, 1,100,000,000
Therefore, the correct order is 3.21, 420,000, 1,100,000,000.
write them all properly in sci notation
3.21 * 10^1
4.2 * 10^5
1.1 * 10^9
Now it is pretty obvious that they are in order already
