It works in theory, and I can see how it would work, but when I substitute numbers for the variables, it doesn't work:
x = 2, y = 3
This was the expression: x2y3+xy
4*27+6 = 114
This was the answer: xy(xy2 + 1)
6(2*9) = 12*54 = 648
6(18) = 108
Did I evaluate the equations wrong? I can't seem to get the same answer for them both...
Let's look at
Are you sure that you plugged everything in, correctly? We know that
Do you think that
is the correct evaluation of
Also, what is the next multiple of 6 after 108?
Assuming that the answer to the first question is "yes", the answer to the second question should tell you that the value of the second factor
Now, go back and re-evaluate
If you're still stuck, please reply and show your all the steps you attempted to correct your work.
