We have a number, in this case, the mass of the elephant that is 5450 kg.
If we want to express it in scientific notation we have to divide the number in two factors: one factor that is a number between 1 and 10 (the base) and another factor that is a power of 10.
We can rearrange the number to convert it into scientific notation as:
[tex]5450=\frac{5450}{1000}\cdot1000=5.45\cdot10^3[/tex]
Then, by multiplying and dividing by 1000, we can convert the number into scientific notation.
Answer: 5450 = 5.45 * 10³ [Third option]
