How many airports have been operationalized under the

√1764 + 35 × 8 + 39 = ?²

18% of 200 - 16% of 150 = ?

25% of 30% of 3/5 of 14500 =?

2(1/3) + 2(5/6) – 1(1/2) = ? – 6(1/6)

7/3 of 4/5 of 15/56 of ? = 83

What will come in place of the question mark (?) in the following expression?

40% of 150 – ?% of 80 = 25% of 400

555.05 + 55.50 + 5.55 + 5 +0.55 = ?       

64.5% of 800 +  36.4% of 1500 = (?)² + 38

What will come in the place of question mark (?) in the given expression?

25% of 1280 + (41 × 4) = ?² 

Simplify the following expression:

((32)⁴ - 1)/33×31× (2¹⁰+1)
