simplify-log_{10}(1.26x10^{-3})

simplify

- lo g_{10} (1.26 x 1 0^{- 3})

- lo g_{10} (1.26) - lo g_{10} (x) + 3

Solution steps

- lo g_{10} (1.26 x \cdot 1 0^{- 3})

Apply log rule:

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

lo g_{10} (1.26 x \cdot 1 0^{- 3}) = lo g_{10} (1.26) + lo g_{10} (x) + lo g_{10} (1 0^{- 3})

= - (lo g_{10} (x) + lo g_{10} (1.26) + 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} (1.26) + lo g_{10} (x) - 3 lo g_{10} (10))

3 lo g_{10} (10) = 3

= - (lo g_{10} (x) + lo g_{10} (1.26) - 3)

Distribute parentheses

= - (lo g_{10} (1.26)) - (lo g_{10} (x)) - (- 3)

Apply minus-plus rules

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

= - lo g_{10} (1.26) - lo g_{10} (x) + 3

lo g_{6} (m) + \frac{2}{3} lo g_{6} (n)

ln (x) + 5 \cdot ln (y) - 6 \cdot ln (z)

ln (\frac{e ^{x}}{3})

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

\frac{14 \cdot 0.89}{60 \cdot 0.58} \cdot ln (\frac{1}{1 - 0.1})
