If x²- 5x + 1 = 0, what is the value of x² + 1/x2?
What will come in place of the question mark (?) in the following question?
24.30% of 372.32 = ?
350% of (450 / 1.5) = ?% of 4200
(5832)1/3 × 10.11 × 11.97 ÷ 16.32 = ? + 45.022
(15 × 225) ÷ (45 × 5) + 480 = ? + 25% of 1240
3/7 of 686 + 133(1/3)% of 33 – 69 =?
√121 + √961− √289 =?2
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 ...
17.8 + 3/7 of 89.6 = ?
√? = 80% of 720 - 22% of 2500
