simplify log_{2}(28.8)-log_{2}(1.8)

Solution

simplify

lo g_{2} (28.8) - lo g_{2} (1.8)

Solution

4

Solution steps

lo g_{2} (28.8) - lo g_{2} (1.8)

Apply log rule:

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

lo g_{2} (28.8) - lo g_{2} (1.8) = lo g_{2} (\frac{28.8}{1.8})

= lo g_{2} (\frac{28.8}{1.8})

\frac{28.8}{1.8} = 16

= lo g_{2} (16)

Factor the number:

16 = 2^{4}

= lo g_{2} (2^{4})

Apply log rule:

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

= 4
