simplify log_{2}(200)

Solution

simplify

lo g_{2} (200)

Solution

3 + 2 lo g_{2} (5)

+1

Decimal Notation

7.64385 \dots

Solution steps

lo g_{2} (200)

Factor the number:

200 = 2^{3} \cdot 25

= lo g_{2} (2^{3} \cdot 25)

Apply log rule:

lo g_{a} (x y) = lo g_{a} (x) + lo g_{a} (y)

lo g_{2} (2^{3} \cdot 25) = lo g_{2} (2^{3}) + lo g_{2} (25)

= lo g_{2} (2^{3}) + lo g_{2} (25)

Apply log rule:

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

lo g_{2} (2^{3}) = 3

= 3 + lo g_{2} (25)

lo g_{2} (25) = 2 lo g_{2} (5)

= 3 + 2 lo g_{2} (5)
