3% of 842 ÷ 2% of 421 = ?

9 × 4⁰ × 24² × 18² = ?²

215 + 378 – 23 + 15 - 27 = ? + 3² + 16²

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

?% of 600 + 15 × 28 = 30% of 1800

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

? = ((180 × 27) ÷ 60) + ((52 × 70) ÷ (13 × 280))³ 

35% of 240 – 6 ² = ? ² – √256

Simplify the following expression:

(16⁴-1)/17×15× (2⁸+1)

36.76 + 2894.713 + 34965.11 =?

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