simplify-log_{10}(1x10^{-3})

simplify

- lo g_{10} (1 x 1 0^{- 3})

- lo g_{10} (x) + 3

Solution steps

- lo g_{10} (1 \cdot x \cdot 1 0^{- 3})

Apply log rule:

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

lo g_{10} (1 \cdot x \cdot 1 0^{- 3}) = lo g_{10} (1) + lo g_{10} (x) + lo g_{10} (1 0^{- 3})

= - (lo g_{10} (x) + lo g_{10} (1) + lo g_{10} (1 0^{- 3}))

Apply log rule:

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

lo g_{10} (1 0^{- 3}) = - 3 lo g_{10} (10)

= - (lo g_{10} (1) + lo g_{10} (x) - 3 lo g_{10} (10))

lo g_{10} (1) = 0

3 lo g_{10} (10) = 3

= - (lo g_{10} (x) + 0 - 3)

Simplify

0 + lo g_{10} (x) - 3 : lo g_{10} (x) - 3

= - (lo g_{10} (x) - 3)

Distribute parentheses

= - (lo g_{10} (x)) - (- 3)

Apply minus-plus rules

- (- a) = a, - (a) = - a

= - lo g_{10} (x) + 3

ln (\frac{3 y}{x ^{5}})

ln (x^{2} - 25) - ln (x + 5)

lo g_{10} (\frac{1}{20})

10 \cdot lo g_{10} (\frac{2 \cdot 1 0 ^{- 2}}{1 0 ^{- 12}})

ln (\frac{4}{13})
