Which one of the following is not among the services of

(23.99)² – (17.99)² + (1378.88 + 44.88) ÷ ? = 607.998

5555.05 + 500.05 + 5000.005 + 5.005 =?

Find the approximate value of Question mark(?). No need to find the exact value.

(34.95 × 7.03) ÷ 5 + 27.98% of 249.88 – √(80.81) = ?

(3375)^1/3 x 12.11 x 6.97divide; 14.32 = ? + 15.022

[(√2024.85 ÷ 3.01) + (35.76 ÷ 11.92)]² × (3/4 of 39.99) = ?

? = 23.08 + 19.99 × 28.07

What approximate value will replace the question mark (?) in the following?

44.87% of (39.85 × ?) – 1520.88 ^0.51 = 1400.8

?% of [(12.96 × 40.05) + 25.08 × 18.96] = 17.96 × 22.05 + 3.05 × 66.96
