We know that if it is a negative exponent that is also an odd number, it will not be the greatest/largest. 2 times 10 is 20 and then 20 to the fourth power is 160,000. 3.8 times 10 equals 38, then we put it to the third power and we will get 54,872. Finally, 7.5 times 10 equals 75 and when we put that to the third power, it becomes 421,875. Therefore, 2 times 10 to the fourth power is the greatest/largest.
