√ [? x 11 + (√ 1296)] = 16

[(36 × 15 ÷ 96 + 19 ÷ 8) × 38] = ?% of 608

154 × 7 + 480 × 5 =?% of 6956

(? + 180 + 13 × 6) ÷ 20 + 3.5 × 512 ^(1/3) = 8²

The value of ((0.27)²-(0.13)²) / (0.27 + 0.13) is:

?² = 37% of 800 – 14 × 18+ 5! - 20

181/8 + 51/4 – 63/8 = ? + 9/2

(125 × 12 × √8100) ÷ 150 = ?

Find the simplified value of the given expression.

{12.75 × √64 + 13.5 × √(√256)} ÷ 6 + 49.5 ÷ 5.5 

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

{180 + (2250/15)} ÷ 11 = ?² + 14
