List 5 numbers that have 3, 5, and 7 as prime factors.

You can simply multiply all the combinations of 3,5, and 7 in pairs:

1) 3 * 5 = 15

2) 3 * 7 = 21

3) 5 * 7 = 35

Don't forget the numbers multiplied to itself:

4) 3 * 3 = 9

5) 5 * 5 = 25

6) 7 * 7 = 49

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
