We know that; (a2 - b2) = (a + b) X (a - b) So, (7.225 + 2.275) X (7.225 - 2.275) = (9.5) X 4.95 = 47.025
?% of (140.31 ÷ 19.97 × 80.011) = 139.98
?% of (742÷ 7.911) = (11.01)2
[√ (121.23)÷ √ (12100.04)]× √ 80.95 = 3/10 + ?÷ 4
...15.12 x 12.02 + 16.94 x 6.12 - 18.93 x 8.89 = ? - 25.07
(14.66)2 + (343.84 ÷ 3.88 - 55.87) = ? + 91.23
(56.04% of 550.06 + 19.92 × 18.13) = ?
20% of 80 × 26% of 65 = ?
[(2/3 of 599.77) + (39.69% of 450.14)] ÷ [(5/8 of 399.79) - √120.91] = ?
