√64 of √225 = √(25 + ?) X 12
350% of (450 / 1.5) = ?% of 4200
42% of 400 + 38% of 800 + ?2 = 728
540240 ÷ 24 ÷ 25 =?
44% of 560 + 68% of 2160 × 5/12 =? + 32% of 920.
72 + 122 - 25% of 600 = ?
√4096 + √3249 = (?)2
? = (√784 - √361) + 102 - 3√512
5.45% of 1854 – 37.5% of 1096 = ? – 48% of 630
[(√576 × √144) ÷ √1296]2 = ? ÷ 3
