1) Question : Which of the following is equivalent to 76000
Explanation: That is true. If we initially start with 76 x 10^3, we can transform it into (76x 10^1) x (10^3 x 10^-1). This is the trick I often use: multiplying simultaneously by 10^1 and 10^-1, 10^2 and 10^-2, 10^3 and 10^-3 would not change anything because it is simply the same as saying multiply
2) Question : Which of the following is equivalent to 56.3?
Explanation: This is right. If we move 2 digits backwards, we will be at 56.3
3) Question : which of the following is equivalent to 2.0 x 10^-2
Explanation: This is the correct answer. Recall that you can multiply by 10^3 as long as you simultaneously multiply by 10^-3. Hence, this could be true. See image below for further clarification
4) Question : which of the following is equivalent to 6.55
Explanation: Recall that we can multiply 6.55 by 10^-4 and then by 10^4, it would have no impact on the final result
5) Question : which of the following is equivalent to 425.2
Explanation: You can multiply 425.2 by 10^2 and by 10^-2 and you will eventually get the same answer.
6) Question : Which of the following is equivalent to 50 x 10^-3
7) Question : which of the following is equivalent to 800.2 x 10^-1
Explanation: Recall that we can multiply this entire equation by 10^3 and 10^-3 simultaneously
8) Question : Which of the following is equivalent to 55.034x 10^4
Explanation: we can multiply this equation by 10^2 and 10^-2
9) Question : which of the following is equivalent to 32.5 x 10^-3
Explanation: Again, recall that we can also multiply by 10 and 10^-1.
10) Question : which of the following is equivalent to 623 x 10^ -5
