A 747 airplane weighs about 600,000 pounds. It can also be expressed as approximately 3 times 10 Superscript n tons. If there are 2,000 pounds in 1 ton, which is the most reasonable value of n?

Step-by-step explanation:

We have the equivalence between tons and pounds, therefore:

600,000 pound = 300 tons

Now, they tell us that:

3 * 10 ^ n = 300

Dividing by 3 the whole equation we have:

10 ^ n = 100

Now how many times must the number 10 be multiplied so that of 100:

10 ^ 2 = 100

Thus:

n = 2

1/4 because there is 4 grades.
