Why can't decimal numbers be represented exactly in binary?
...oating point can be exactly represented.
Let's look at it another way - in base 10 which you're likely to be comfortable with, you can't express 1/3 exactly. It's 0.3333333... (recurring). The reason you can't represent 0.1 as a binary floating point number is for exactly the same reason. You can re...
Are 2^n and n*2^n in the same time complexity?
...nge of variable. Let m = 2ⁿ. Then n⋅2ⁿ = ( log₂m )⋅m (taking the base-2 logarithm on both sides of m = 2ⁿ gives n = log₂m ), and you can easily show that m log₂m grows faster than m.
