I don’t know how to find the location of w please help :(

A33 gram sample of a substance that's used to detect explosives has a k-value of 0.1473. n = noekt no = initial mass (at time t = 0) n = mass at time t k = a positive constant that depends on the substance itself and on the units used to measure time t = time, in days

Find the value of x. give reasons to justify your solutions! l, m ∈ kn

Having a hard time understanding this question (see attachment).
