simplify-log_{10}(6.2\times 10^{-8})

simplify

- lo g_{10} (6.2 \cdot 1 0^{- 8})

- lo g_{10} (6.2) + 8

Decimal Notation

7.20760 \dots

Solution steps

- lo g_{10} (6.2 \cdot 1 0^{- 8})

Apply log rule:

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

lo g_{10} (6.2 \cdot 1 0^{- 8}) = lo g_{10} (6.2) + lo g_{10} (1 0^{- 8})

= - (lo g_{10} (6.2) + 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} (6.2) - 8 lo g_{10} (10))

8 lo g_{10} (10) = 8

= - (lo g_{10} (6.2) - 8)

Distribute parentheses

= - (lo g_{10} (6.2)) - (- 8)

Apply minus-plus rules

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

= - lo g_{10} (6.2) + 8

lo g_{10} (\frac{x ^{3} y ^{4}}{z ^{2}})

ln (5 x y)

lo g_{b} (2 b^{5})

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

x (ln (x) - ln (y))
