simplify ln(x^7sqrt(7-x))

Solution

simplify

ln (x^{7} 7 - x)

Solution

7 ln (x) + ln (7 - x)

Solution steps

ln (x^{7} 7 - x)

Apply log rule:

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

ln (x^{7} 7 - x) = ln (x^{7}) + ln (7 - x)

= ln (x^{7}) + ln (- x + 7)

Apply log rule:

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

ln (x^{7}) = 7 ln (x)

= 7 ln (x) + ln (7 - x)
