25% of 400 + 3 × 102 = ?2
[∛(91125/19683 )- ∛(3375/5832 ) ] × ∛(512/9261) = ? - √(484/3969)
16 × ? + 36% of 250 = 410
`(256/6561)(1/4) = ?`
√10000 × √8100 - (50)² = √(?) + (80)²
(180 ÷ 22 ) ÷ (60% of 30) = (? ÷ 2)
74% of 2840 + 80% of 1640 - ?= 47²
[4(1/3) + 4(1/4)] × 24 – 62 = ?2
19 × ? = 361 ÷ 19
555.05 + 55.50 + 5.55 + 5 +0.55 = ?
