Question 793445
3*ln(4) - 2 ( ln(10) - ln(2) )


3*ln(4) - 2 ( ln(10/2) )


3*ln(4) - 2 ( ln(5) )


3*ln(4) - 2*ln(5)


ln(4^3) - ln(5^2)


ln(64) - ln(25)


<font color="red">ln(64/25)</font> ... See note below


Note: This is where you made the mistake. You used the rule ln(x)-ln(y) = ln(x/y) improperly
