Answer:

x = - 15  

Step-by-step explanation:

given,                                        

log₂ (1 - x) =  4                                    

using logarithmic identity

logₐ x = b                                      

x = aᵇ                                                  

converting into exponential form as the base is 2

1 - x = 2⁴  

1 - x = 16

x = 1 -16

x = - 15                      

hence the required solution of X is x = - 15
