simplify-log_{10}(3.2*10^{-7})

simplify

- lo g_{10} (3.2 \cdot 1 0^{- 7})

- lo g_{10} (3.2) + 7

Decimal Notation

6.49485 \dots

Solution steps

- lo g_{10} (3.2 \cdot 1 0^{- 7})

Apply log rule:

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

lo g_{10} (3.2 \cdot 1 0^{- 7}) = lo g_{10} (3.2) + lo g_{10} (1 0^{- 7})

= - (lo g_{10} (3.2) + lo g_{10} (1 0^{- 7}))

Apply log rule:

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

lo g_{10} (1 0^{- 7}) = - 7 lo g_{10} (10)

= - (lo g_{10} (3.2) - 7 lo g_{10} (10))

7 lo g_{10} (10) = 7

= - (lo g_{10} (3.2) - 7)

Distribute parentheses

= - (lo g_{10} (3.2)) - (- 7)

Apply minus-plus rules

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

= - lo g_{10} (3.2) + 7

- \frac{1}{3} ln ∣ x + 2 ∣ + \frac{1}{3} ln ∣ x - 1 ∣

0.082 \cdot ln (0.1 \cdot 0.4)

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

ln (x^{3} y)

0.0259 \cdot ln (\frac{2.8 \cdot 1 0 ^{19}}{7 \cdot 1 0 ^{15}})
