## Homework Statement

[tex]\int[/tex]10[tex]^{t}[/tex]dt t = [1,2]

## Homework Equations

I know that [tex]\int[/tex](a[tex]^{x}[/tex])dx = [tex]\frac{(a^x)}{ln(x)}[/tex] + C and x[tex]\neq[/tex] 1

## The Attempt at a Solution

I could do this problem as indefinate, but since the restraints include a "1", I can't plug it into the the integral because it will result in a "0" being in the denominator. The answer in the back of the book shows:

[tex]\frac{90}{ln(10)}[/tex]

Should I be using a substitution rule somewhere?
