simplify 3ln(pq)+4ln(pq^2)

simplify

3 ln (pq) + 4 ln (p q^{2})

ln (p^{7} q^{11})

Solution steps

3 ln (pq) + 4 ln (p q^{2})

Apply log rule:

a lo g_{c} (b) = lo g_{c} (b^{a})

3 ln (pq) = ln ((pq)^{3})

= ln ((pq)^{3}) + 4 ln (p q^{2})

Apply log rule:

a lo g_{c} (b) = lo g_{c} (b^{a})

4 ln (p q^{2}) = ln ((p q^{2})^{4})

= ln ((pq)^{3}) + ln ((p q^{2})^{4})

Apply log rule:

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

ln ((pq)^{3}) + ln ((p q^{2})^{4}) = ln ((pq)^{3} (p q^{2})^{4})

= ln ((pq)^{3} (p q^{2})^{4})

Simplify

(pq)^{3} (p q^{2})^{4} : p^{7} q^{11}

= ln (p^{7} q^{11})

lo g_{e} (\frac{5204}{5101})

lo g_{10} (2 π \cdot 802 \cdot 5.03 \cdot 9.566)

ln (156 e^{5})

6 lo g_{c} (y) - \frac{1}{3} lo g_{c} (w) + 4 lo g_{c} (x)

ln (x^{2} - 9) - ln (3 + x)
