Answer:
n = 20
Step-by-step explanation:
note that 1024 = , thus
=
Since the bases on both sides are equal (2) equate the exponents
= 10 ( multiply both sides by 2 )
the answer is above.
Since the only numbers that are not 0 appear in the groups 5 < d ≤ 10 to 30 < d ≤ 35 the range is 5 < d ≤ 35.
5 times as many should be your answer.
