Solution steps

20 lo g_{10} (\frac{2}{π})

Apply log rule:

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

lo g_{10} (\frac{2}{π}) = lo g_{10} (2) - lo g_{10} (π)

= 20 (lo g_{10} (2) - lo g_{10} (π))

4 ln (4 x)

ln (\frac{3}{x ^{2} + 1})

2 ln (x + 3) - ln (x)

2 lo g_{7} (x + 1) + lo g_{7} (3)

1 + ln (2^{5}) - 5 ln (\frac{5}{2})
