simplify-log_{10}(7.83*10^{-8})

simplify

- lo g_{10} (7.83 \cdot 1 0^{- 8})

- lo g_{10} (7.83) + 8

Decimal Notation

7.10623 \dots

Solution steps

- lo g_{10} (7.83 \cdot 1 0^{- 8})

Apply log rule:

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

lo g_{10} (7.83 \cdot 1 0^{- 8}) = lo g_{10} (7.83) + lo g_{10} (1 0^{- 8})

= - (lo g_{10} (7.83) + lo g_{10} (1 0^{- 8}))

Apply log rule:

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

lo g_{10} (1 0^{- 8}) = - 8 lo g_{10} (10)

= - (lo g_{10} (7.83) - 8 lo g_{10} (10))

8 lo g_{10} (10) = 8

= - (lo g_{10} (7.83) - 8)

Distribute parentheses

= - (lo g_{10} (7.83)) - (- 8)

Apply minus-plus rules

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

= - lo g_{10} (7.83) + 8

ln (8 \cdot 12)

ln (\frac{( 75 + x )}{75})

\frac{1}{ln ( 2 )} \cdot ln (\frac{4}{3})

(0.287) ln (\frac{500}{200}) - (1.05) ln (\frac{680}{980})

lo g_{e} (25) + lo g_{e} (4)
