simplify log_{5}((25)/(sqrt(x+9)))

simplify

lo g_{5} (\frac{25}{x + 9})

2 - lo g_{5} (x + 9)

Solution steps

lo g_{5} (\frac{25}{x + 9})

Apply log rule:

lo g_{a} (\frac{x}{y}) = lo g_{a} (x) - lo g_{a} (y)

lo g_{5} (\frac{25}{x + 9}) = lo g_{5} (25) - lo g_{5} (x + 9)

= lo g_{5} (25) - lo g_{5} (x + 9)

lo g_{5} (25) = 2

= 2 - lo g_{5} (x + 9)

lo g_{10} (y) + 15 lo g_{10} (z)

ln (\frac{e ^{8}}{7})

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

ln (\frac{m}{8} (p - 9))

4 - \frac{3}{2} + ln \frac{3}{2} - ln ∣ 4 ∣
