log_{2}(x+3)=log_{2}(7)

lo g_{2} (x + 3) = lo g_{2} (7)

x = 4

Solution steps

lo g_{2} (x + 3) = lo g_{2} (7)

Apply log rules

x + 3 = 7

Solve

x + 3 = 7 : x = 4

x = 4

Verify Solutions:

x = 4

True

The solution is

x = 4

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

3.3 = - lo g_{10} (x)

ln (7 x + e) = 5

lo g_{10} (2 x + 4) = 1 + lo g_{10} (x)

ln (x) = 1.5
