Question

log(x+5)-log(x)=3

Answer 1

log a-log b=log=a/b

Answer 2

log a-log b = log a/b

Answer 3

log(x+16)/x=1

Answer 4

so
it is log((x+16)/x)=1
now
log of 10 base 10=1
so
log[(x+16)/x]=log10
equating LHS and RHS
x+16/x=10
x+16=10x
9x=16
x=16/9
:)

Answer 5

\[\log(x+16)-\log(x) = \log \frac{ x+16 }{ x }\]

Answer 6

\[\log \frac{ x+16 }{ x } = 1\]

\[\frac{ x + 16}{ x } = 10\]

Answer 7

Nw find x..)
