Given two infinite decimals a = .3939393939... and b = .67766777666... , their sum a + b a. can be defined precisely by using successively better approximations. b. is not a real number because the pattern may not be predictable indefinitely. c. is not a number because not all infinite decimals are real numbers. d. is not defined because the sum of a rational and irrational number is not defined.Given two infinite decimals a = .3939393939... and b = .67766777666... , their sum a + b a. can be defined precisely by using successively better approximations. b. is not a real number because the pattern may not be predictable indefinitely. c. is not a number because not all infinite decimals are real numbers. d. is not defined because the sum of a rational and irrational number is not defined.
