simplify-log_{10}(2*10^{-5})

simplify

- lo g_{10} (2 \cdot 1 0^{- 5})

- lo g_{10} (2) + 5

Decimal Notation

4.69897 \dots

Solution steps

- lo g_{10} (2 \cdot 1 0^{- 5})

Apply log rule:

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

lo g_{10} (2 \cdot 1 0^{- 5}) = lo g_{10} (2) + lo g_{10} (1 0^{- 5})

= - (lo g_{10} (2) + 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} (2) - 5 lo g_{10} (10))

5 lo g_{10} (10) = 5

= - (lo g_{10} (2) - 5)

Distribute parentheses

= - (lo g_{10} (2)) - (- 5)

Apply minus-plus rules

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

= - lo g_{10} (2) + 5

lo g_{10} (x^{3} y^{2})

lo g_{6} (k^{2} - 36) - lo g_{6} (k) - 6

lo g_{19} (\frac{20000}{20}) + 1

6 ln (x) - 3 ln (y)

lo g_{4} (8) + 2 lo g_{4} (5)
