Answer:
Explanation:
The idea of scientific notation is that number is expressed between 1 and 9. 54 in that form is 5.4 But since we moved the decimal to get that number between 1 and 9, we have to add an exponent to a power of 10. 5.4 times 10 is 54 so that means we moved the decimal to a single power of 10.
In scientific notation, our number is 5.4 × 10¹
Again, 10 to the first power is 10, and if you multiply 5.4 by 10, you get 54.
