simplify log_{4}(128)-log_{4}(2)

Solution

simplify

lo g_{4} (128) - lo g_{4} (2)

Solution

3

Solution steps

lo g_{4} (128) - lo g_{4} (2)

Apply log rule:

lo g_{a} (x) - lo g_{a} (y) = lo g_{a} (\frac{x}{y})

lo g_{4} (128) - lo g_{4} (2) = lo g_{4} (\frac{128}{2})

= lo g_{4} (\frac{128}{2})

\frac{128}{2} = 4^{3}

= lo g_{4} (4^{3})

Apply log rule:

lo g_{a} (a^{b}) = b

= 3
