simplify 4log_{b}(x)+7log_{b}(z)

simplify

4 lo g_{b} (x) + 7 lo g_{b} (z)

lo g_{b} (x^{4} z^{7})

Solution steps

4 lo g_{b} (x) + 7 lo g_{b} (z)

Apply log rule:

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

4 lo g_{b} (x) = lo g_{b} (x^{4})

= lo g_{b} (x^{4}) + 7 lo g_{b} (z)

Apply log rule:

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

7 lo g_{b} (z) = lo g_{b} (z^{7})

= lo g_{b} (x^{4}) + lo g_{b} (z^{7})

Apply log rule:

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

lo g_{b} (x^{4}) + lo g_{b} (z^{7}) = lo g_{b} (x^{4} z^{7})

= lo g_{b} (x^{4} z^{7})

ln (4 i)

ln (b) + 2 ln (c) - 3 ln (d)

lo g_{b} (\frac{x ^{3} \cdot y}{z ^{2}})

4 lo g_{b} (y) + 7 lo g_{b} (z)

lo g_{7} (\frac{w ^{2}}{v})
