simplify-log_{10}(2.85*10^{-2})

simplify

- lo g_{10} (2.85 \cdot 1 0^{- 2})

- lo g_{10} (2.85) + 2

Decimal

1.54515 \dots

Solution steps

- lo g_{10} (2.85 \cdot 1 0^{- 2})

Apply log rule:

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

lo g_{10} (2.85 \cdot 1 0^{- 2}) = lo g_{10} (2.85) + lo g_{10} (1 0^{- 2})

= - (lo g_{10} (2.85) + lo g_{10} (1 0^{- 2}))

Apply log rule:

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

lo g_{10} (1 0^{- 2}) = - 2 lo g_{10} (10)

= - (lo g_{10} (2.85) - 2 lo g_{10} (10))

2 lo g_{10} (10) = 2

= - (lo g_{10} (2.85) - 2)

Distribute parentheses

= - (lo g_{10} (2.85)) - (- 2)

Apply minus-plus rules

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

= - lo g_{10} (2.85) + 2

\frac{π}{6} ln (5)

6 lo g_{c} (x) - \frac{1}{2} lo g_{c} (z) + 7 lo g_{c} (w)

ln (\frac{1}{29})

ln (\frac{25}{22.5})

9 x + 3 ln (x - 1) - 3 ln (2) + 4 ln (x)
