Question 949614
    Given log 2 = 0.3010, log 3= 0.4771 and log 7= 0.8451, find the value of log sqrt(140)
.
{{{log(sqrt(140))}}}
{{{log(140^(1/2))}}}
{{{(1/2)log(140)}}}
{{{(1/2)log(7*20)}}}
{{{(1/2)log(7*2*10)}}}
{{{(1/2)(log(7)+log(2)+log(10))}}}
{{{(1/2)(0.8451+0.3010+1)}}}
{{{(1/2)(2.1461)}}}
{{{(1/2)(2.1461)}}}
{{{1.07305}}}
