**Problem**

**Problem**

=

i.e. =

i.e. =

Canceling the common term

, we get

=

**(Ans: 2)**

*Estimated Time to arrive at the answer = 100 seconds*

**Using Technique**

[contentblock id=google-adsense-post]

Just rewrite the expression as:

=

Now observe the variable ‘y’ and its powers

LHS =>

RHS =>

(after opening the brackets)

This means that the variable ‘y’ cancels out and so the answer should have only the variable ‘x’. The only option that satisfies this condition is option ‘2’.

**(Ans: 2)**

*Estimated Time to arrive at the answer = 10 seconds*
