simplify-log_{10}(0.8*10^{-9})

simplify

- lo g_{10} (0.8 \cdot 1 0^{- 9})

- lo g_{10} (0.8) + 9

Decimal Notation

9.09691 \dots

Solution steps

- lo g_{10} (0.8 \cdot 1 0^{- 9})

Apply log rule:

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

lo g_{10} (0.8 \cdot 1 0^{- 9}) = lo g_{10} (0.8) + lo g_{10} (1 0^{- 9})

= - (lo g_{10} (0.8) + lo g_{10} (1 0^{- 9}))

Apply log rule:

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

lo g_{10} (1 0^{- 9}) = - 9 lo g_{10} (10)

= - (lo g_{10} (0.8) - 9 lo g_{10} (10))

9 lo g_{10} (10) = 9

= - (lo g_{10} (0.8) - 9)

Distribute parentheses

= - (lo g_{10} (0.8)) - (- 9)

Apply minus-plus rules

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

= - lo g_{10} (0.8) + 9

ln (\frac{v ^{2}}{v ^{1}})

ln (12) + ln (14)

1 + 2 lo g_{2} (π) - lo g_{2} (15)

4186 (ln (323) - ln (373))

ln (\frac{51.65}{50.35})
