As (x + y + z) = (80 – 35 – 45) = 0
So, x³ + y³ + z³ = 3xyz
So, (x³ + y³ + z³) = {3 × 80 × (-35) × (-45)} = 378000
So, required value = {(x³ + y³ + z³)/10³} = (378000/1000) = 378
{(8× 8 + 3 × 39) - 620 ÷ 20} = ?
48 ÷ 6 × √25 + 13 × 8 = ?
Find the simplified value of the following expression:
14.25 × 32 – 11.4 × 15 + 8 – 712 ÷ 8 + 34.15 × 20 – 27 × 21 = ?
...[564 + 32 of 18 × 9 ÷ 12 + 162 ] ÷ 4 = ?
(64/25)? × (125/512)?-1 = 5/8
2856 ÷ 34 = ?% of 240
58% of 3300 - ?% of 2900 = 1740
