8(3/4) + 5(1/6) – 4(3/4) = ?
What should come in place of (?) question mark in the given expression.
(2⁵ × 3⁴) ÷ (6³) = ?
1280 ÷ 8 + 490 ÷ √49 + ? = 150 * 2
What will come in place of (?) in the given expression.
{(60% of 250) + √144} ÷ (3² - 4) = ??% of 740 – 8% of 650 = 7.2
9 × 4 ? ÷ 16 = 144
82.3 × 644.7 × 723.4 × 815.85 = 72?
Simplify the given expression:
[(2.3)3 + (15.9) ³ + (3.7) ³ – 3 × 2.3 × 15.9 x 3.7)] / [(2.3) ² + (15.9) ² + (3.7) ² – 2.3 ...
447.8 × 441.2 ÷ 445 = 44 × 44?
What should come in place of (?) question mark in the given expression.
