simplify ln|x+2|+ln|x-2|

Solution

simplify

ln ∣ x + 2 ∣ + ln ∣ x - 2 ∣

Solution

ln (∣ x + 2 ∣ ∣ x - 2 ∣)

Solution steps

ln ∣ x + 2 ∣ + ln ∣ x - 2 ∣

Apply log rule:

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

ln ∣ x + 2 ∣ + ln ∣ x - 2 ∣ = ln (∣ x + 2 ∣ ∣ x - 2 ∣)

= ln (∣ x + 2 ∣ ∣ x - 2 ∣)
