simplify log_{7}(49x)

Solution

simplify

lo g_{7} (49 x)

Solution

2 + lo g_{7} (x)

Solution steps

lo g_{7} (49 x)

Factor the number:

49 = 7^{2}

= lo g_{7} (7^{2} x)

Apply log rule:

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

lo g_{7} (7^{2} x) = lo g_{7} (7^{2}) + lo g_{7} (x)

= lo g_{7} (7^{2}) + lo g_{7} (x)

Apply log rule:

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

lo g_{7} (7^{2}) = 2

= 2 + lo g_{7} (x)
