Answer:
256
Step-by-step explanation:
This question seems technical but it's actually simple depending on how much you understand it
2[3(42+1)]-2
We can actually see to brackets in the question...
So to solve we will have to solve those bracket one after another
Let's start with the inner bracket
3(42+1)
3(43)
129
Then let's move to the next bracket
2[129]
258
Then to the last part of the question
Which is 258-2
=256
Therefore the final answer is 256... you can see that the question is simple only when you understand it...
Hope it has helped you
