Countable and uncountable sets: a. show that if a is countably infinite, then a x a is countably infinite. b. is the set of all bit strings of finite length countable or uncountable? if countable, show how you would enumerate the set. if uncountable, give a proof by diagonalization. c. is the set of all bit strings of infinite length countable or uncountable? if countable, show how you would enumerate the set. if uncountable, give a proof by diagonalization.

answer: the anser is 3

step-by-step explanation:

c- 2o is equal to 9

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)
