Question

____× 105 is 3,000 times greater than 2.3 × 102 and is _____ times greater than 1.38 × 101.

Answer 1

For this case we must calculate the values of the unknowns.
 We have then:
 $x * 10 ^ 5$ is 3,000 times greater than$2.3 * 10 ^ 2$
 We have the following equation:
 $(x * 10 ^ 5) / (2.3 * 10 ^ 2) = 3000$
 From here, we clear the value of x:
 $x = (10 ^ 2/10 ^ 5) * (2.3 * 3000) x = 6.9$
 Then, on the other hand we have:
 "and is _____ times greater than 1.38 × 101"
 That is, we have the following equation:
 $(6.9 * 10 ^ 5) / (1.38 * 10 ^ 1) = y$
 The value of y is:
 $y = 50000$
 Answer:
 6.9 × 105 is 3,000 times greater than 2.3 × 102 and is 50000 times greater than 1.38 × 101.
