How many subsets of four different numbers whose product is a square can be chosen from {1,2,3,4,5,6,7,8,9}?

idc

step-by-step explanation:

idk

- both graphs increase on their domain.

- the graphs of both functions have the same x-intercept.

- neither graph has a y-intercept.

1. perpendicular

2. parallel

3. perpendicular

step by step solution :

step   1   :

1.1     4 = 22

(4)3 = (22)3 = 26

equation at the end of step   1   :

  ((23) • 26)2

step   2   :

equation at the end of step   2   :

  (23 • 26)2

step   3   :

final result :

  218
