(2^(4-1)^2)/(2^(3-2))
1- 2^8
2- 2^7
3-2^6
4-2^5

I keep getting 2^6, OA is 2^8, can someone please clarify or let me know what I am doing wrong. PEMDAS right?

The main point here is that:
2^3^2 is NOT equal to (2^3)^2
1. 2^3^2 = 2^9
2. (2^3)^2 = 2^6
If you see that, then it's
(2^3^2) / 2^1 = 2^9 / 2 = 2^8
2^3^2 is NOT equal to (2^3)^2
1. 2^3^2 = 2^9
2. (2^3)^2 = 2^6
If you see that, then it's
(2^3^2) / 2^1 = 2^9 / 2 = 2^8
