simplify log_{b}(9)+log_{b}(10)

simplify

lo g_{b} (9) + lo g_{b} (10)

lo g_{b} (90)

Solution steps

lo g_{b} (9) + lo g_{b} (10)

Apply log rule:

lo g_{a} (x) + lo g_{a} (y) = lo g_{a} (x y)

lo g_{b} (9) + lo g_{b} (10) = lo g_{b} (9 \cdot 10)

= lo g_{b} (9 \cdot 10)

Multiply the numbers:

9 \cdot 10 = 90

= lo g_{b} (90)

lo g_{6} (x y z^{4})

6.1 + lo g_{10} (\frac{27}{1.41})

5 lo g_{8} (c^{3} d^{2}) + 3 lo g_{8} (c d^{7})

ln (\frac{x}{1 - 5 x})

lo g_{7} (2) + lo g_{7} (a + 4 b)
