Solve the equation : 8+10^x=1008

Marizza181 [45]

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 + $10^{x}$ = 1008

Subtract 8 from both sides.

$10^{x}$ = 1000

We know that 10³ = 1000

x = 3
