simplify-log_{10}(2.5*10^{-8})

simplify

- lo g_{10} (2.5 \cdot 1 0^{- 8})

- lo g_{10} (2.5) + 8

Decimal

7.60205 \dots

Solution steps

- lo g_{10} (2.5 \cdot 1 0^{- 8})

Apply log rule:

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

lo g_{10} (2.5 \cdot 1 0^{- 8}) = lo g_{10} (2.5) + lo g_{10} (1 0^{- 8})

= - (lo g_{10} (2.5) + lo g_{10} (1 0^{- 8}))

Apply log rule:

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

lo g_{10} (1 0^{- 8}) = - 8 lo g_{10} (10)

= - (lo g_{10} (2.5) - 8 lo g_{10} (10))

8 lo g_{10} (10) = 8

= - (lo g_{10} (2.5) - 8)

Distribute parentheses

= - (lo g_{10} (2.5)) - (- 8)

Apply minus-plus rules

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

= - lo g_{10} (2.5) + 8

3 ln (\frac{14}{13})

ln (6) + ln (x) - ln (2)

3 (ln (5) - ln (2)) + \frac{9}{10}

ln (9) - ln (16)

lo g_{4} (\frac{6}{5})
