Solution steps

20 lo g_{10} (\frac{0.15}{4 π})

Apply log rule:

lo g_{c} (\frac{a}{b}) = lo g_{c} (a) - lo g_{c} (b)

lo g_{10} (\frac{0.15}{4 π}) = lo g_{10} (0.15) - lo g_{10} (4 π)

= 20 (lo g_{10} (0.15) - lo g_{10} (4 π))

ln (x \frac{5}{2 x + 3})

- ln (1 - x) + ln (1 + x)

ln (\frac{1}{5 e})

\frac{1}{4} (ln (3 tan (\frac{x}{2} + 1)) - ln (tan (\frac{x}{2} + 3))) + c

0.423 - \frac{0.0592}{2} lo g_{10} (\frac{0.075}{0.1})
