5.45% of 1854 – 37.5% of 1096 = ? – 48% of 630
[4(2/3) + 5(1/6)] × 45% of 240 = ?
(√ 121 x 41) + (3√343 x √289 ) = ? x 19  Â
(53 + 480 ÷ 4)% of 20 = ?% of 70
√10000 x √8100 - (50)² = √(?) + (80)²
(0.1 × 0.2 × 0.3) + (0.3 × 0.4 × 0.5) =?
((1024)n/5 × (42n+1 ))/(16n × 4n-1 ) = ?
Simplify the following expression:
  (525 +175) ² - (525 – 175) ² / (525 × 175)
`2(1/3)` + `4(1/4)` + `4(2/3)` + `8(7/6)` + ? = `4(3/5)xx4(1/2)`
