1. Which is larger?
2.75 x 10^3 or 4.92 x 10^2
To compare these two numbers, you need to convert them to scientific notation and compare the exponents.
2.75 x 10^3 can be written as 2.75 x 1000 = 2750
4.92 x 10^2 can be written as 4.92 x 100 = 492
Since 2750 is larger than 492, 2.75 x 10^3 is larger than 4.92 x 10^2.
