You can choose what "blank" is.

parthkohli · Answer

Though, I'd prefer if the blanks become $3$, $a^2 $ and $a^3$. This'd make life easier than before.

anonymous · Answer

How would you work it out?

parthkohli · Answer

By simplifying.

anonymous · Answer

Can you please show me the steps ?

parthkohli · Answer

Let's make it look like$${ 3 \over \boxed3  } + {\boxed{a^2} \over a^2} - {\boxed{a^3 }\over a^3}$$

parthkohli · Answer

What're $\large{3 \over 3}$ , $\large{a^2 \over a^2}$ and $\large{a^3 \over a^3}$?
