Hi there.
I'm just going to put the answer for now. I might come back and edit my answer if I figure out how to solve this the long way.
All I did was figure out what exponent you raise 10 to.
10³ = 1000
So, we now have 8 + 10³ = 1008
Edit:
I did it on paper - here it is broken down.
8 + [tex] 10^{x} [/tex] = 1008
Subtract 8 from both sides.
[tex] 10^{x} [/tex] = 1000
We know that 10³ = 1000
x = 3
