in my psychology textbook this is called the bystander effect with the answer choices you have i would say diffusion responsibility, but i am not sure. It is definitely not A though.

How do you just know this though?

okay. how would you solve: 2log(subscript6)(4) - (1/3)log(sub6)(8) = log(sub6)(x)

so the coefficient of a log function are the same as writing it as an exponent of x in the equation: log(subb)x = y ? therefore, Clog(subb)x = y is the same as log(subb)x^(C) = y ?
