simplify log_{10}(5*10^{-2})

Solution

simplify

lo g_{10} (5 \cdot 1 0^{- 2})

Solution

lo g_{10} (5) - 2

+1

Decimal Notation

- 1.30102 \dots

Solution steps

lo g_{10} (5 \cdot 1 0^{- 2})

Apply log rule:

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

lo g_{10} (5 \cdot 1 0^{- 2}) = lo g_{10} (5) + lo g_{10} (1 0^{- 2})

= lo g_{10} (5) + lo g_{10} (1 0^{- 2})

Apply log rule:

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

lo g_{10} (1 0^{- 2}) = - 2 lo g_{10} (10)

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

2 lo g_{10} (10) = 2

= lo g_{10} (5) - 2
