Question 215485
(a) Express:{{{D = 10(Log(I)-Log(I[0]))}}} as a single logarithm: Applying the quotient rule for logarithms, we get:
{{{highlight(D = 10(Log(I/I[0])))}}} For part (b), substitute {{{I = 100}}} and {{{I[0] = 1}}}
(b) {{{D = 10(Log(100/1))}}}
{{{D = 10(Log(100))}}}
{{{D = 10(2)}}}
{{{highlight(D = 20)}}}
