Question

a^2+b^2=13 and x3+y^3=65 then find (a+b)(x+y)

Answer 1

Step-by-step explanation:

> stands for +, < stands for –, + stands for  , 

stands for X, – stands for =, X stands for > and =

stands for <, then which of the following statement

is correct in each question

35. (1) 7 + 7 > 4 = 3 (2) 8 > 8 < 8 + 8 = 17

(3) 14 < 14 + 14 = 13 (4) 6 6 > 6 + 6 = 6

Answer (2)

Sol. 8 > 8 < 8 + 8 = 17

36. (1) 2 > 4 < 8 6 = 32

(2) 8 > 8 < 6 > 6 = 18

(3) 6 6 > 4 4 > 2 6 4 = 104

(4) All of the above

Answer (4)

37. (1) 52< 24 >28 < 26 – 4 5 > 1

(2) 88 + 4 > 4 + 4 × 7  2  2 > 3 2

(3) 19 > 14 2 < 46 + 2 = 25

(4) 3  10 < 5 > 4 < 7 × 8

Answer (3)

Sol. 19 > 14 2 < 46 + 2 =
