Question 1
a) log A=log B+ log C
log A=log (BC )
A=BC
b) loga F=loga 3−loga c
loga F+ loga c=loga 3
log a ( Fc)=log a 3
Fc=3
c) log C=−1
3 log g
log C=log (g
−1
3 )
C=g
−1

d) log Q=2 log p+1
log Q=log p2+ log 10
¿ log 10 p2
Q=10 p2
Question 2
a) 50 ×e−0.03 x=0.05
e−0.03 x=0.05
50 =0.001
ln e−0.03 x=ln 0.001
−0.03 x=ln0.001
x= ln 0.001
−0.03
b) 81 e0.3 x−27=0
81 e0.3 x=27
e0.3 x=27
81
e0.3 x=1
