Given:
(4k⁷)³ = 4n(k⁷)³
Note that (aˣ)ⁿ = aˣⁿ
Expand the left and right sides.
4³k²¹ = 4nk²¹
Divide each side by k²¹.
4³ = 4n
Divide each side by 4.
4² = n
Therefore
n = 4² = 16
Answer: n = 16
(5•4)-8 the answer is 12 because 5 times 4 is 20. Then 20 minus 8 is 12.
Answer:
65% of the original amount.
Explanation:
Let's say that the original amount is 100%; therefore, if we subtract 35% from the original amount we have


Hence, if the amount of fruit decreased by 35%, then we have 65% of the original amount left.
22 + (30 - 4) divided by 2
30 - 4 = 26
26/2 = 13
22 + 13 = 35
35
18 + (22 - 4) divided by 6
22 - 4 = 18
18 divided by 6 = 3
18 + 3 = 21
21
17% is the answer to the question
