Ok I got you

YRJ8498:

Nothing further can be done

YRJ8498:

its the same

SwaggyMark:

why

SwaggyMark:

it needs to be written in exponential form

surjithayer:

\[10^{x+3}=8\]

SwaggyMark:

how u got that

yy:

8 -- 3 to get x

yy:

sorry divied

YRJ8498:

Use the definition of a logarithm, logb(x)=y⟹ by=x, to convert from the logarithmic form to the exponential form. 83=x

surjithayer:

\[10^{x}=a\] take log of both sides \[\log(10^{x})=\log a \] xlog(10)=log a log 10=1 log a=x

YRJ8498:

There's no choices right you have to write/type it?

yy:

why did you close it???

surjithayer:

\[10^x \times 10^3=8,1000 \times 10^x=8,10^x=\frac{ 8 }{ 1000}\]
