simplify-log_{10}(2.2*10^{-5})

simplify

- lo g_{10} (2.2 \cdot 1 0^{- 5})

- lo g_{10} (2.2) + 5

Decimal Notation

4.65757 \dots

Solution steps

- lo g_{10} (2.2 \cdot 1 0^{- 5})

Apply log rule:

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

lo g_{10} (2.2 \cdot 1 0^{- 5}) = lo g_{10} (2.2) + lo g_{10} (1 0^{- 5})

= - (lo g_{10} (2.2) + 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} (2.2) - 5 lo g_{10} (10))

5 lo g_{10} (10) = 5

= - (lo g_{10} (2.2) - 5)

Distribute parentheses

= - (lo g_{10} (2.2)) - (- 5)

Apply minus-plus rules

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

= - lo g_{10} (2.2) + 5

ln^{2} (x) + 3 ln (x)

ln (b \cdot e^{- 2})

2 lo g_{6} (w - 2) - 3 lo g_{6} (w) + 9

ln (12) + 8 x + 5 - ln (3)

ln (4 e 4)
