Answer:
We have for velocity of package v= 20 - 9.8t and for distance from the ground y = h + 20t - 4.9t2.
We have y = 0 and t = 18.0 s we have h = 4.9·182 - 20·18 = 1227.6 m.
Velocity at landing v = 20 - 9.8·18 = - 156.4 m/s
For this case we have that by definition of multiplication of powers of the same base, the same base is placed and the exponents are added:

So, we can rewrite the given expression as:

So, if
