Check all the statements that are true:

a. you can block covert a binary number to octal by grouping the binary digits into blocks of 3 and converting each block into an octal digit.
b. if p and q are distinct primes, then the lcm of p2q and pq2 is pq.
c. an integer is divisible by b if the last digit in its base-b expansion is zero.
d. if a has n distinct prime factors and b has m distinct prime factors and n> m, then ab has at least m and at most n distinct prime factors.
e. there is a way to perform block conversion of binary number into decimal.
f. if a has n distinct prime factors and b has m distinct prime factors and n> m, then ab has at least n and at most n+m distinct prime factors.
g. the lcm of two distinct prime numbers is their product.
h. the gcd of p2q3 and p4q is p6q4.
i. using fast modular exponentiation, we can computer an mod b in order of log(n) steps.
j. the euclidean algorithm always terminates because the remainders are integers, get smaller with each step and are bounded below by 1.

You drop a rubber ball off the roof of a 50 meter high building onto a paved parking lot. it bounces back up with every bounce, but not quite all the way back up to you. after the first bounce it bounces back only 80 percent of the distance it was dropped from. the pattern continues, meaning after every bounce it comes up to just 80 percent of the previous maximum height. so if before the first bounce the height is 50 meters, what height does the ball reach after the fifth bounce? round your answer to one decimal place and chose the correct response from the choices below:
