D: I don't know this yettt...... I sowwy.

OpenStudy (asnaseer):

is this the question?\[\log_7(1-x)=4\]

OpenStudy (anonymous):

@asnaseer YESSSSS

OpenStudy (asnaseer):

ok, use the log rule that if:\[\log_ab=c\]then this implies:\[b=a^c\]

OpenStudy (anonymous):

so there you would get 1-x=2401 1 from both sides leaves you with -x=2400. So now it equals a negative right?

OpenStudy (asnaseer):

yes - your answer is correct

OpenStudy (anonymous):

thamk you sooo much
