Question

Square numbers of the numbers from 1 to 20 are given in the table given below.
(I) Write the digits on ones place in square from given table in the form of set A. A = {0, 1, 4, .........)
(ii) Write the numbers between 0 and 9 in B which are not in A.

Answer 1

i) A = {0, 1, 4, 5, 6, 9}

ii) B = {2, 3, 7, 8}

Step-by-step explanation:

Square numbers of the numbers from 1 to 20 = { 1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144, 169, 196, 225, 256, 289, 324, 361, 400}

i) A is the set of the digits of ones place in the square numbers.

A = {0, 1, 4, 5, 6, 9}

ii) B is the set of numbers between 0 and 9 which are not in A.

B = {2, 3, 7, 8}

Hence, A = {0, 1, 4, 5, 6, 9}

            B = {2, 3, 7, 8}
