Please explain how it is (ln 4)

¡Ò^8 2 x^-1 dx= (ln 8) ¨C (ln 2)

=(ln 4)

It's not possible to see the problem because the symbols are incomprehensible. Please retype the equation so that we can help you.

• math calculus -

ln (8) - ln (2) = ln (4)

How is this possible

• math calculus -

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.
