Which of the following are examples of presentation

What will be the approximate value of the following questions.

(89.90% of 479.88 - 2/5 of 400.11)² ÷ (50.11% of 359.77 + √224.85) = ?

80.08% of 1250.25 + 64.02% of 1200 = 24.02 × 36.025 + ?% of 2259.98

672.35 ÷ 24.03 × 12.99 – 1288.28 ÷ 13.94 = ?

11.06 ² – 7.12 × 4.88 + 9.96 = 12.22 × ? 

(256.19 ÷ 63.99) ^2.05 X (7.99) = 2 ^{? + 2.05}

19.22 × 11.99 + 142.15 = ?

37.06% of 783.45 + 2125% of 51.89 = ?

(4096)^1/3 × 10.11 × 11.97 ÷ 24.32 = ? + 15.022

√ ({(5.5 × 2.3) × √ (728.91))} = 3(1/7) ÷ ?/28

`sqrt(224.991)` + (3.81008)² = ? `-:` `1/6.0001`
