(a)For a part we will use the property
loga(x×y)=loga(x)+loga(y)
So we have ,log8x+log8(p)=log8(x×p)
log8(xp)
b) in second part it is already given
This is the property of log that log(1) at any base is zero.
So
logx(1)=0
(2)
To find log form
formula
if Mn=p
then n=log Mp
hence m is the base of the log
(a)
5x=25
x=log525
hence base =5
(b)
(41)3=641
3=log(41)641
hence base=41
(3)
if ax=ay, then x=y
hence given equation 63x+5=6x−2
3x+5=x−2
2x=−7
x=−27
