What are the values of k, if the roots of the equation x² + 2(k - 4)x + 2k = 0 are equal?
2916 ÷ 54 = ? + 27
1365 ÷ 15 + (? ÷ 5) = 62 × 3.5
{5% of (20 × 25) + 6% of (30 ×35)} ÷ 11 = ?
What is the value of √75 + √108?
20% of 1500 – 75% of 200 = 125% of ?
500% of (121.8 + 16.4 – 28.2) = ? × 2
Solve: 3/4÷2/3
15% of 2400 + (√ 484 – √ 256) = ?
225÷ 25 x 21 - 30 = ? + √2209 - √7744
