simplify-log_{10}(8.5*10^{-6})

simplify

- lo g_{10} (8.5 \cdot 1 0^{- 6})

- lo g_{10} (8.5) + 6

Decimal Notation

5.07058 \dots

Solution steps

- lo g_{10} (8.5 \cdot 1 0^{- 6})

Apply log rule:

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

lo g_{10} (8.5 \cdot 1 0^{- 6}) = lo g_{10} (8.5) + lo g_{10} (1 0^{- 6})

= - (lo g_{10} (8.5) + lo g_{10} (1 0^{- 6}))

Apply log rule:

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

lo g_{10} (1 0^{- 6}) = - 6 lo g_{10} (10)

= - (lo g_{10} (8.5) - 6 lo g_{10} (10))

6 lo g_{10} (10) = 6

= - (lo g_{10} (8.5) - 6)

Distribute parentheses

= - (lo g_{10} (8.5)) - (- 6)

Apply minus-plus rules

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

= - lo g_{10} (8.5) + 6

2.4 ln (3) + ln (2)

\frac{1}{3} (3 ln (x + 4) + ln (x) - ln (x^{2} - 8))

6 ln (\frac{a}{5}) + 4 ln (7 b)

8 \cdot lo g_{b} (x) + 9 \cdot lo g_{b} (y) - 4 \cdot lo g_{b} (z)

ln (1 i)
