Answer:
18^5
Step-by-step explanation:
18^9 ÷ 18^4
= 18 ^ (9-4)

X=
Negative two because you cannot have a smaller number in front of a larger number. If you do have a smaller number in front of a larger one the answer will always be negative, Thus the answer 12 - 14 is -2 ( negative two)
Answer:
The sum of the first 10 terms is 4092
Step-by-step explanation:
We can use the formula for a partial sum of a geometric series of first term and common ratio r, which is given by:
Therefore, in this particular case where we add the first 10 terms of a geometric series with first term 4 and the common ratio 2, we have:
