展开 ln(q)(-1/a-1)-ln(-a)

解答

展开

ln (q) (- \frac{1}{a} - 1) - ln (- a)

- \frac{ln ( q )}{a} - ln (- a q)

求解步骤

ln (q) (- \frac{1}{a} - 1) - ln (- a)

乘开

ln (q) (- \frac{1}{a} - 1) : - \frac{ln ( q )}{a} - ln (q)

= - \frac{ln ( q )}{a} - ln (q) - ln (- a)

化简

- \frac{ln ( q )}{a} - ln (q) - ln (- a) : - \frac{ln ( q )}{a} - ln (- a q)

= - \frac{ln ( q )}{a} - ln (- a q)
