simplify-log_{10}(5.45*10^{-5})

simplify

- lo g_{10} (5.45 \cdot 1 0^{- 5})

- lo g_{10} (5.45) + 5

Decimal Notation

4.26360 \dots

Solution steps

- lo g_{10} (5.45 \cdot 1 0^{- 5})

Apply log rule:

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

lo g_{10} (5.45 \cdot 1 0^{- 5}) = lo g_{10} (5.45) + lo g_{10} (1 0^{- 5})

= - (lo g_{10} (5.45) + 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} (5.45) - 5 lo g_{10} (10))

5 lo g_{10} (10) = 5

= - (lo g_{10} (5.45) - 5)

Distribute parentheses

= - (lo g_{10} (5.45)) - (- 5)

Apply minus-plus rules

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

= - lo g_{10} (5.45) + 5

lo g_{5} (\frac{2 x ^{3}}{4 y})

\frac{3}{2} + ln (2) - ln (3) + 2 ln (3) - 3 ln (2)

ln (0.005) - ln (0.05)

ln (\frac{39}{50})

ln (8) + ln (7)
