Find the pairs of equal sets, if any, give reasons: A = {0}, B = {x : x > 15 and x < 5}, C = {x : x – 5 = 0 }, D = {x: x² = 25}, E = {x : x is an integral positive root of the equation x² – 2x –15 = 0}.
In the following, state whether A = B or not:
Are the following pair of sets equal ? Give reasons.
From the sets given below, select equal sets : A = { 2, 4, 8, 12}, B = { 1, 2, 3, 4}, C = { 4, 8, 12, 14}, D = { 3, 1, 4, 2} E = {–1, 1}, F = { 0, a}, G = {1, –1}, H = { 0, 1}
Show that the set of letters needed to spell " CATARACT " and the set of letters needed to spell " TRACT" are equal.
