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

48 ÷ 4 × (3 + 5) – 6² + 10 = ?

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

9 ^{(? + 12)} = 3 ^{(14 + 17 - 11)}

(2500 ÷ √625) × √(42.25) = ? ÷ 4

(15/8) x [6924 – 2124] + 910 = ? + 190

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

41² + 25% of 2400 = ? + 1131

37% of 810 – 32% of 460.5 = ?

√3970 × √730- √2400 =?

Simplify the following expression:

1280 ÷ 8 + 490 ÷ √49 + ? = 150 * 2
