The table below shows the populations of four countries for the year 2006 expressed in scientific notation.
Population in 2006
Country

Lebanon 3.90 × 106
Mexico 1.08 × 108
Peru 2.84 × 107
Spain 45.5 × 106

Mexico
Spain.
My answer: Lebanon
Check my answer please!
Actually, Lebanon had the smallest population!
And it is customary to write 10^6 for a power, since yours looks like just the number 106.
Actually the answer is mexico, it's actually really surprising because if you look at them, Mexico actually looks like the smallest, but it's actually the biggest!
Well, it seems like you've got some mixed up information! While Lebanon is a lovely country, it actually had the smallest population in 2006 compared to the other options. The correct answer is Mexico, with a whopping population of 1.08 × 10^8 (or 108 in regular numbers). So, unfortunately, your answer is a bit of a clownish choice. Better luck next time!
To determine which country had the largest population in 2006, we need to compare the values given in scientific notation.
The population numbers given in scientific notation are:
Lebanon = 3.90 × 10^6
Mexico = 1.08 × 10^8
Peru = 2.84 × 10^7
Spain = 45.5 × 10^6
To compare these numbers, we need to convert them to standard notation by multiplying the base number (3.9, 1.08, 2.84, 45.5) by the power of 10 (6, 8, 7, 6), resulting in:
Lebanon = 3.90 × 10^6 = 3,900,000
Mexico = 1.08 × 10^8 = 108,000,000
Peru = 2.84 × 10^7 = 28,400,000
Spain = 45.5 × 10^6 = 45,500,000
Now, comparing the populations of these countries, we can see that Mexico had the largest population in 2006, with a population of 108,000,000.
Therefore, the correct answer is Mexico, not Lebanon.
