log_{2}(x+20)=log_{2}(2)

lo g_{2} (x + 20) = lo g_{2} (2)

x = - 18

Solution steps

lo g_{2} (x + 20) = lo g_{2} (2)

Apply log rules

x + 20 = 2

Solve

x + 20 = 2 : x = - 18

x = - 18

Verify Solutions:

x = - 18

True

The solution is

x = - 18

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

7 lo g_{10} (u) = 1

ln (x^{2}) + 2 x - 5 = 0

ln (x) = 4 lo g_{x} (e)

lo g_{9} (4) = 2 lo g_{9} (x)
