simplify-log_{10}(5.1*10^{-4})

simplify

- lo g_{10} (5.1 \cdot 1 0^{- 4})

- lo g_{10} (5.1) + 4

Decimal Notation

3.29242 \dots

Solution steps

- lo g_{10} (5.1 \cdot 1 0^{- 4})

Apply log rule:

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

lo g_{10} (5.1 \cdot 1 0^{- 4}) = lo g_{10} (5.1) + lo g_{10} (1 0^{- 4})

= - (lo g_{10} (5.1) + lo g_{10} (1 0^{- 4}))

Apply log rule:

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

lo g_{10} (1 0^{- 4}) = - 4 lo g_{10} (10)

= - (lo g_{10} (5.1) - 4 lo g_{10} (10))

4 lo g_{10} (10) = 4

= - (lo g_{10} (5.1) - 4)

Distribute parentheses

= - (lo g_{10} (5.1)) - (- 4)

Apply minus-plus rules

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

= - lo g_{10} (5.1) + 4

2 lo g_{3} (2 x)

\frac{1}{5} lo g_{6} (8) - (lo g_{6} (5) + lo g_{6} (3))

lo g_{10} (5) - 2 lo g_{10} (3)

0.6 lo g_{2} (0.6) + 0.4 lo g_{2} (0.4)

lo g_{10} (25) + lo g_{10} (4) + lo g_{10} (2)
