How can you write the expression (-15)(-15)(-15)(-15) using exponents?

a. -15^4
b.(-15)^4
c. 4(-15)
d. 4(-15)^4

d. 4 (-15)^4 would be the answer

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
