Information and Communication Technology MCQ - Number System
Unit digit in 398 = Unit digit in
(34)24 x Unit digit in(32) = 9
:. Dividing 398 by 5 or dividing 9 by 5,
we get the remainder 4.
(34)24 x Unit digit in(32) = 9
:. Dividing 398 by 5 or dividing 9 by 5,
we get the remainder 4.
∴ Product of two whole numbers is 24.
  Possible pairs = (1, 24), (2, 12), (3,8), (4,6)
∴ Sum of these pairs
 (1, 24) = 1 + 24 = 25
 (2,12) = 2 + 12 = 14
 (3,8) = 3 + S = 11, (4,6) = 4 + 6 = 10
∴ Smallest possible sum = 10
  Possible pairs = (1, 24), (2, 12), (3,8), (4,6)
∴ Sum of these pairs

 (3,8) = 3 + S = 11, (4,6) = 4 + 6 = 10
∴ Smallest possible sum = 10
x = 597 x 1022 + 73.5 x 1021
= 5970 X 1021 + 73.5 X 1021
= 6043.5 X 1021 = 6.0435 X 1024
On compare with 6.0435 x 10m,
we get m = 24
= 5970 X 1021 + 73.5 X 1021
= 6043.5 X 1021 = 6.0435 X 1024
On compare with 6.0435 x 10m,
we get m = 24
From the given options,√11 cannot be written in the form of p/q.So, it is an irrational number.
