Question

Can any one help me....?

Answer 1

Options are B and C....
I want to know why D is wrong...?

Answer 2

>>I want to know why D is wrong...?

Suppose x = -5.

Then, √( (-5)^2) = √25 = 5. -5 is not equal to 5.

Answer 3

I would say B, but I am not for sure

Answer 4

ok thanq u.....
i got it....

Answer 5

B must be true because if x is negative, then x^3 is also negative AND x^2 must be positive. A negative number is less than a postive number.

Answer 6

C must be true because x + (1/x) = (x^2 + 1) / x.

If x is negative, then x^2 + 1 (numberator) is always positive.
The denominator is always negative if x is negative.
And, a positive divided by a negative is always negative.
