Answer: No, it is actually 6,780,000
Step-by-step explanation: Since 10^6 is 1 million, we can do 6.78 times 1 million to get 6,780,000.
Hope this helps! :)
Expressions can be represented as logarithms and exponents
Rogelio argument is correct
<h3>How to determine if Rogelio's claim is true</h3>
The logarithmic equation is given as:

Apply logarithm rule, to rewrite the logarithmic equation

Evaluate the individual logarithmic expressions

Evaluate the quotient (i.e. divide the expression)

The above equation shows that
is between 6 and 7
Hence, Rogelio argument is correct
