Find the Value of 

√(?) ² = √7396 - √6889

65% of ? = 50 + 20 × 4

Evaluate:

7.5 + 12 ÷ (4 × 1.5) − 2.4

280 – 70 × 14 ÷ 5 = ? – 21 of 3

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

(12³ ÷ 6²) × 15 - 120 = ?

√729 × 5 + 270 - 3 ÷ ∛27 + 4 × ? = 484

654.056 + 28.9015 × 44.851 – 43.129 =?

If 1.123 × 3.211 = 3.122 + ______________, then the number in blank space is

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

(240% of 175 ÷ √16) X 6 + 80% of 400 = ?³ + 179 + 42

? ÷ 62 × 12 = 264
