log base 10?
OpenStudy (anonymous):
How do you solve it? I'm not sure where to start.
OpenStudy (anonymous):
first begging by writen it clear it is \[\log_{10}7^{n} = (2/3)\log_{10}7^{8} ???? \]
OpenStudy (anonymous):
Where does the 10 come from?
OpenStudy (anonymous):
the logarithmic functions has a base usually when u write log it meants that it has base 10

OpenStudy (anonymous):
yes, n is the exponent for the left side of the equation
OpenStudy (anonymous):
and the base of the exponent?
OpenStudy (anonymous):
n is the exponent; and its base?

the base is 7
OpenStudy (anonymous):
so the base of the log function is 10
OpenStudy (anonymous):
and 7 is the base of n
OpenStudy (jdoe0001):
$$
log_7(n)=\cfrac{2}{3}log_7(8) ?
$$
OpenStudy (anonymous):
it would be great if the student write the eqation like jdoe001 or like me
