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

435 ÷ 29 X 792 ÷ 44 = √(? + 14) + 3⁵ + 221 ÷ 17

162 ÷ [51 – {29 – (9 – 6̅ ̅+̅ ̅7̅ )}]=?

 {(481  + 426) 2 - 4 × 481 × 426} = ?

180 % of 45 + √144 × 8 = ?²  + 80 % of 70

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

64² - 36² = ? X √1225

500% of (121.8 + 16.4 – 28.2) = ? × 2

√196 + (0.25 × 144) + 19 = ? + 7²

√(?) ² = √7396 - √6889

36% of 250 + 26 ÷ 2 × ? = 207
