Answer:
The last one is correct.
Step by step:
Each income has ONLY one outcome.
4 ^ (1/7 ) is the 7th root of 4 or the 3rd box
4 ^ (7/2) is 4 to the 7th power then the square root or the 2nd box
7 ^ (1/4) is the 4th root of 7 or the 4th box
7 ^ (1/2) is the square root of 7 or the 6th box
(3x + 1) + 44 = 90
(3x + 1) = (90 - 44) = 46
3x = 45
x = 45 / 3
x = 15
For a solution of 'all real numbers' to occur, you must end up with a statement that is true no matter what
example
simplifying results in x=x or 8=8 or 0=0 or something liek that
an example equation would be 2(x+1)=2x+2, simplifies to x=x or 2=2 or 0=0
no solution is when you get a false statement from simplifying
example, 3=4 or -1=0
an example equation could be 2(x+1)=2x+3, it simplifies to 2=3 which is false
