Which of the following is true regarding the solution to the logarithmic equation below?
log2(x+11) = 4
X+ 11 = 24
X+ 11 = 16
X= 5
X= 5 is not a true solution because logs (16) + 2
X= 5 is not a true solution because log (16) 4
X=5 is a true solution because log (16) = 4
X= 5 is a true solution because log4(16) = 2
