1. Find the constant k so that:
log_(y^5) (x^3)= k * log_y(x)
for all positive real numbers y doesn't equal to 1
2. log_4(11)+ log_8(11)+ log_64(11)
( Keep the answer in log_b(n) format please)
then what is the sum of b and m.
(BTW I tried changing the base to 2, but I still couldn't derive the answer)
1. By properties of logs, k = 5/3.
2. The number is log_128 (11), so b + m = 139.
