simplify ln(6.8*10e^{-2})

Solution

simplify

ln (6.8 \cdot 10 e^{- 2})

Solution

ln (6.8) + ln (10) - 2

+1

Decimal Notation

2.21950 \dots

Solution steps

ln (6.8 \cdot 10 e^{- 2})

Apply log rule:

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

ln (6.8 \cdot 10 e^{- 2}) = ln (6.8) + ln (10) + ln (e^{- 2})

= ln (6.8) + ln (10) + ln (e^{- 2})

Apply log rule:

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

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

= ln (6.8) + ln (10) - 2 ln (e)

2 ln (e) = 2

= ln (6.8) + ln (10) - 2
