24. Kuoministers

answer in book is 2^ n-3?

25. AravindG

but i am sure of my answer ! check the question again

26. Kuoministers

2^3 times (2n)^2 times 2^ -n opps one difference

27. AravindG

:O

28. Kuoministers

is there any difference?

29. Kuoministers

30. AravindG

i dont see any diff in question

31. Kuoministers

anyways thanks

$2^3 \times (2n)^2 \times 2^{-n}$$= 2^{3-n} \times 2^2n^2$$=2^{3-n+2}n^2$$=...$
