Given that , find in terms of u,
i)
ii)
iii)
...
log9(x)=u
exponential form:9^u=x
..
log3(x)
exponential form:(3^2)^u=3^2u=9^u=x
log3(x)=2u
..
log9(27x)
log9(x)+log9(27)
log9(x)+log9(9)+Log9(3)
log9(27x)=u+1+1/2=u+3/2
..
log2(81)
sorry, I don't know how to do this one.
Let me know when you find the right ans.
