simplify log_{10}(3)-2log_{10}(5)

simplify

lo g_{10} (3) - 2 lo g_{10} (5)

lo g_{10} (\frac{3}{25})

Decimal Notation

- 0.92081 \dots

Solution steps

lo g_{10} (3) - 2 lo g_{10} (5)

Apply log rule:

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

- 2 lo g_{10} (5) = - lo g_{10} (5^{2})

= lo g_{10} (3) - lo g_{10} (5^{2})

Apply log rule:

lo g_{a} (x) - lo g_{a} (y) = lo g_{a} (\frac{x}{y})

lo g_{10} (3) - lo g_{10} (5^{2}) = lo g_{10} (\frac{3}{5 ^{2}})

= lo g_{10} (\frac{3}{5 ^{2}})

5^{2} = 25

= lo g_{10} (\frac{3}{25})

lo g_{10} (\frac{10 z}{8})

lo g_{11} ((x + y) \cdot z)

lo g_{2} (\frac{4}{x + 6})

lo g_{2} (n^{2} \cdot lo g_{2} (n))

lo g_{10} (\frac{1}{3}) + lo g_{10} (2)
