Hey!
----------------------------------------------
Solution:
Put all the answer choices into expanded form.
3^9 = 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3
1^8 = 1 x 1 x 1 x 1 x 1 x 1 x 1 x 1
9^3 = 9 x 9 x 9
8^1 = 8
----------------------------------------------
Answer:
We can see that the only way to write to write 9 x 9 x 9 in exponential form is c) 9^3

Hope This Helped! Good Luck!
Answer:
n = 2
Step-by-step explanation:
Expand the brackets.
1/2n - 2 - 3 = 3 - 2n - 3
Add or subtract terms.
1/2n - 5 = -2n
Add 5 and 2n on both sides.
1/2n + 2n = 5
5/2n = 5
Multiply both sides by 2/5.
n = 5 × 2/5
n = 10/5
n = 2
