simplify log_{10}(2*10^{-7})

Solution

simplify

lo g_{10} (2 \cdot 1 0^{- 7})

Solution

lo g_{10} (2) - 7

+1

Solution steps

lo g_{10} (2 \cdot 1 0^{- 7})

Apply log rule:

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

lo g_{10} (2 \cdot 1 0^{- 7}) = lo g_{10} (2) + lo g_{10} (1 0^{- 7})

= lo g_{10} (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} (2) - 7 lo g_{10} (10)

7 lo g_{10} (10) = 7

= lo g_{10} (2) - 7
