Find the missing number.
The correct answer is 120 . Logic: (Column wise) (3)2 = 9 – 1 = 8 (5)2 = 25 + 1 = 26 (7)2 = 49 – 1 = 48 (9)2 = 81 + 1 = 82 (11)2 = 121 – 1 = 120 (13)2 = 169 + 1 = 170
If x = 107, then find the value of x(x2 - 12x + 48) ?
If x – 1/x = 9, then x3 – 1/x3 is:
If x = 15, find x5 - 16x4 + 16x3 - 16x2 + 16x - 16 = ?
if 3y-3/y=8 then find the value of y ² +1/y²
If 9x2 + 16y2 = 24xy, then find the ratio of ‘x’ and ‘y’, respectively.
If 0.125x3 +0.216y3 = 210 and 0.25x2 + 0.36y2 = 10.30 then find the value of 0.5x + 0.6y.
1/3 + 1/15 + 1/35 + 1/63 + 1/99 = ?
