Identify the mirror image of the following figure when

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

(?³ - 888) ÷ 4 + 70 = 345 - 65

4567.89 - 567.89 - 678.89 = ?

70 % of 640 + 75 % of 360 - 19 × 12 = ?

1549.8 ÷ 8.2 + 65.6 × 55 = (? × 4) + (42 × 30.5)

What value should come in the place of (?) in the following questions?

√(60 + 8² + 101) * 5 = ?

Simplify the expression:

(5x + 15) / (x² + 3x)

(6630 ÷ 13 + 6120 ÷ 12) ÷ (17 × 3) = ? 

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

Find the value of ?

{[(864 ÷ 18) ÷ 8] ÷ 3} + 11² – 2³ = ?
