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

simplify

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

- 3 lo g_{10} (2) + 10

Solution steps

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

Apply log rule:

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

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

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

Apply log rule:

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

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

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

10 lo g_{10} (10) = 10

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

lo g_{10} (8) = 3 lo g_{10} (2)

= - (3 lo g_{10} (2) - 10)

Distribute parentheses

= - (3 lo g_{10} (2)) - (- 10)

Apply minus-plus rules

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

= - 3 lo g_{10} (2) + 10

ln (γ (a))

20 lo g_{10} (\frac{2}{π})

ln (\frac{3}{x ^{2} + 1})

2 ln (x + 3) - ln (x)

2 lo g_{7} (x + 1) + lo g_{7} (3)
