Question

what is the value of ln(2*10³)?and how to find the value of ln???

Answer 1

$log(ab) = log(a) + log(b) \\m log(a) = log( {a}^{m} ) \\ \\ log_{e}(10) =2.303 \\ log_{e}(2) = 0.693 \\ \\ log_{e}{(2 \times {10}^{3}) } \\ = log_{e}(2) + log_{e}( {10}^{3} ) \\ = log_{e}(2) + 3 log_{e}( {10}) \\ = 0.693 + 3(2.303) \\ = 7.602$
$<b > <red> You can find log values using log table$

Answer 2

In2*103 =2.303log 2*103

2.303*(3-0.3010)

2.303*2.699
