The exponent of the number in scientific notation is 6.
First, let's write our two limits in scientific notation.
The lower bound is one million, which is:
1,000,000 = 1*10^6
(the exponent is equal to the number of digits after the first one).
The upper bound is ten million, which is written as:
10,000,000 = 1*10^7
Now, if Jerome's number is between these two, then the exponent must be 6, it can't be other number. Because if it is smaller than 6, then the number is smaller than one million, and if it 7 or larger, then it is larger than ten million.
