Please explain how it is (ln 4)
¡Ò^8 2 x^-1 dx= (ln 8) ¨C (ln 2)
It's not possible to see the problem because the symbols are incomprehensible. Please retype the equation so that we can help you.
ln (8) - ln (2) = ln (4)
How is this possible
one of the most basic log rules is
Log(A/B) = LogA - LogB, as long as the base of the log is the same
since 8/2 = 4 it fits the pattern
you might also try to verify it on your calculator.
