Answer 2

★Answer :-

It is given that is a natural number it means it starts from 1 and these are all positive

$\sf{\ a^{3}-\dfrac{1}{\ a^{3}}}$

$\sf{\dfrac{\ a^{6}-1}{\ a^{3}}}$

• If a is any natural number then if we will put any natural number on the place of hi so we will get the value always greater than or equal to 0

Example :-

If , a = 1

$\implies\sf{\dfrac{\ 1^{6}-1}{\ 1^{3}}}$

$\implies\sf{\dfrac{1-1}{1}}$

$\implies\sf{\dfrac{0}{1}}$

$\implies\sf{0}$

• For smallest value of a it is zero so we can say that the upcoming value will be always greater than or equal to zero
