1) [2 + 1/(2) ]2 = ?A) 5/2 B) 11/2 C) 7/2 D) 9/2
2) If x = (2 + 1)/(2 - 1) y = (2 - 1) /(2 + 1) then (x2 + y2) =?A) 40 B) 48 C) 46 D) 44
Answer & Explanation
Answer: 48 ( x2 = (2 + 1)/(2 - 1) * (2 + 1)/(2 + 1) = 4 + 2(2) y2 = (2 - 1)/(2 + 1) * (2 - 1)/(2 - 1) = 4 - 2(2) (x2 + y2) = (4 + 2(2))2 + (4 - 2(2)2 = 48)
3) a*b*c = (x+5)(y+3)/(z+2) then (3 * 15 * 2)A) 6 B) 8 C) 9 D) 10
4) 6 = 2.449 then 3 2/23) =?A) 1.22 B) 1.2245 C) 1.23 D) 1.26
