V(e) = e^3.
For any value of e, (the edge length), just cube it to get the volume. Easy
V(-2) = -8
V(-1) = -1
V(0) = 0
V(1) = 1
V(2) = 8
V(3) would be 27...etc
It doesn't make sense to use a negative or zero value for e (since you can't have a length like that), so technically there should be a restriction of e > 0.
To find the edge length given the volume, we would just solve for e.
V = e³
Take the cube root of each side...
∛V = ∛e³
∛V = e
Write as e(V) = ∛V.

Answer:
21 + x = 35
Step-by-step explanation:
if you do inverse operations you will find that x = 35-21
which is 14
Answer:
24
Step-by-step explanation:
The question is saying, how many three digit numbers can be made from the digits 3, 4, 6, and 7 but there can't be two of the same digit in them. For example 346 fits the requirements, but 776 doesn't, because it has two 7s.
Okay, on to the problem:
We can do one digit at a time.
First digit:
There are 4 digits that we can choose from. (3, 4, 6, and 7)
Second digit:
No matter which digit we chose for the first digit, there is only going to be 3 of them left, because we already chose one, and you can't repeat that same digit. So there are 3 options.
Third digit:
Using the same logic, there are only 2 options left.
We have 4 choices for the first digit, 3 choices for the second, and 2 for the third.
Hence, this is 4 * 3 * 2 = 24 three-digit numbers that can be made.
The square root of 16 is 4
