How do you do question number 11 without guessing. is there a technique that i can use for it.

well here's a calculator mehtod:
use logarithms.
write them in the logratitm form:
11(A) Log20.125 = m
enter this in calculator n get the value of m.
similarly for (b)
simplif first:
2^6n=512
Log2512= n
divide the value of n with 6.
