simplify-log_{10}(3.4x10^{-5})

simplify

- lo g_{10} (3.4 x 1 0^{- 5})

- lo g_{10} (3.4) - lo g_{10} (x) + 5

Solution steps

- lo g_{10} (3.4 x \cdot 1 0^{- 5})

Apply log rule:

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

lo g_{10} (3.4 x \cdot 1 0^{- 5}) = lo g_{10} (3.4) + lo g_{10} (x) + lo g_{10} (1 0^{- 5})

= - (lo g_{10} (x) + lo g_{10} (3.4) + lo g_{10} (1 0^{- 5}))

Apply log rule:

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

lo g_{10} (1 0^{- 5}) = - 5 lo g_{10} (10)

= - (lo g_{10} (3.4) + lo g_{10} (x) - 5 lo g_{10} (10))

5 lo g_{10} (10) = 5

= - (lo g_{10} (x) + lo g_{10} (3.4) - 5)

Distribute parentheses

= - (lo g_{10} (3.4)) - (lo g_{10} (x)) - (- 5)

Apply minus-plus rules

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

= - lo g_{10} (3.4) - lo g_{10} (x) + 5

e^{20} + ln (18 x)

ln (y) + ln (\frac{y}{2})

ln (e^{in} (e^{in (e x)}))

ln (\frac{0.3892}{0.3659})

ln (\frac{x}{y})
