Which number is the largest? (4 points)

1.2 × 10^4, 4.5 × 10-3, 3.8 × 10^3, 7.5 × 10^3

1.2*10^4 is the largest

Step-by-step explanation: When asked a question like this the key is to look at the powers. A power of 4.5*10-3 is much smaller than 1.2*10^4 regardless of the numbers in front because the power represents how many zeros are in the number. In this circumstance just look for the biggest power.
