simplify ln(4u^{-2})

Solution

simplify

ln (4 u^{- 2})

Solution

2 ln (2) - 2 ln (u)

Solution steps

ln (4 u^{- 2})

Apply log rule:

lo g_{c} (ab) = lo g_{c} (a) + lo g_{c} (b)

ln (4 u^{- 2}) = ln (4) + ln (u^{- 2})

= ln (4) + ln (u^{- 2})

Apply log rule:

lo g_{a} (x^{b}) = b \cdot lo g_{a} (x)

ln (u^{- 2}) = - 2 ln (u)

= ln (4) - 2 ln (u)

ln (4) = 2 ln (2)

= 2 ln (2) - 2 ln (u)
