P × Q = PQ(P + Q), Similarly, P x Q = (2 × 2) = 4 x (2 + 2) = 4 x 4 = 16 P x Q = (4 × 4) = 16 x (4 + 4) = 16 x 8 = 128 Hence, required answer = 16 + 128 = 144
255 × 8 + 386 × 5 =? % of 7940
1500 ÷ 15 + 1000 ÷ √100 + ? = 250 * 3
222 - 122 + 162 = (?)2 – 29

48 ÷ 6 × √25 + 13 × 8 = ?
10 × 100 ÷ 5 + 9 = ?
3 √(432 – 13 + 9 × 32) = ?
√(82 × 7 × 52 - 175) = ?
