Quant Exponent Question

What is the answer and how to solve these type of exponent questions which are in the form a^b^c^d
Edit:
The answer is 1, which is easy to calculate, what I want to understand is how do we generally solve exponent questions of the type: a^b^c^d.

Is the answer 1?

You can rewrite 4 as 2^2. So the numerator will be 2^32. The denominator is also 2^32 as 2^5 = 32. The answer should be 1.

My aim wasn’t to find the answer, but a method that can be applied to exponent questions like a^b^c^d.
Sorry, I guess my question misled you, I will edit it.

If an exponent is of the form a^b^c^d, start by calculating c^d first and then move downwards.
For example if there’s an exponent 1^2^2^2, calculate 2^2 first which will give you 4. Then our exponent reduces to 1^2^4. Then calculate 2^4 = 16. Now we have reduced this exponent to 1^16 = 1

But what if the number is big, like 32^16^16^8 ? Calculating wouldn’t be an option, right ? So how would you solve this one ?

They would never ask such question in gre

:v: Thanks

Yes!!

Such questions will not be asked but if you still want to solve, you can start by converting those numbers into powers of 2 then using the identities of exponents to multiply or add the powers and then recursively move down the chain.

I know the method, but I am unable to get 2^32 rather I am getting 2^16 (The denominator and numerator both simplify to 2^32).
That is the reason I asked this doubt.


I hope this helps you!
