in exact form

HI!!

3. misty1212

try $$u=\log_5(x)$$

4. misty1212

you get $du=\frac{dx}{\ln(5)x}$ and you are pretty much done

5. misty1212

change the limits of integration while you are at it. get $\frac{1}{\ln(5)}\int_0^2 (u^2+\sqrt7 u+6)du$

6. triciaal

do you understand what @misty1212 has?

7. joachimngeny

trying it now.

8. triciaal

ok

9. triciaal

Why do you change the upper and lower bound to 2 and 0? @Michele_Laino @misty1212 @triciaal

@joachimngeny do you need explanation?
