The answer says "if x=0 or 1" however x >0 is defined above.

Hi Mona, thanks for the input. You can replace "if x=0 or 1" with simply "if x=1 ...".

It is clearly said that x>0 then how will the argument if x=0 hold good. The answer is B?

Sheeman, the explanation should read:
"Now, if x = 1, then the expressions are equal. However, for any other positive value of x, the expressions are unequal."

The answer is d but I don't understand why column b would not be correct

Darrielle, is x=1, for example, the columns would be equal, and B is not larger than A.

Where do you get x=1? I don't see that in the answer key. All I see is x=0 but the question is not saying x=0 it's saying X>0. Also when facing questions like x>0 or x

The solution should have said "Now, if x = 1, then the expressions are equal. However, for any other positive value of x, the expressions are unequal."

Is it x^(3+1) and 4^(4+1) OR x^(3)+1 and x^(4)+1?

Hi Arseniy,
It is x^(3)+1 and x^(4)+1. That is, the 1s are not exponents. To make it clearer, we can write the 1s first:
1 + x^3
[read, 1 plus x cubed]
and
1 + x^4
[read, 1 plus x to the fourth power]
