hvordan løser jeg denne?
[sub]0[/sub] [symbol:integral] [sup]ln2[/sup] 6e[sup]2x[/sup]dx=
lett integral

[tex]\int 6\cdot e^{2x}\rm{d}x= 6\cdot \frac12e^{2x}+C=3\cdot e^{2x}+C[/tex]
Løser bestemt:
[tex]\int_0^{\ln(2)}6\cdot e^{2x}\rm{d}x=\left[3e^{2\ln(2)}-3e^{2\cdot0}\right]_0^{\ln2}=[3\cdot 4-3\cdot 1]=9[/tex]

The square root of Chuck Norris is pain. Do not try to square Chuck Norris, the result is death.

hvordan får du e[sup]2ln(2)[/sup] til å bli 4? Noen lette logaritmeregler?
[tex]e^{2ln(2)}=e^{\ln(2^2)}=2^2[/tex]
