Graphite, also known as 'plumbago' or black lead, is an allotrope of carbon that has a metallic appearance and is used in various industrial applications.
If P3 + 3P2 + 3P = 7, then the value of P2+ 2P is –
If (a - b - c) = 6, and (ab - bc + ca) = 117, then find the value of (a2 + b2 + c2)
If x4 + x - 4 = 47 then find the value of (x + x-1).
For a =-4 and b = 5, value of a² – b² is:
((99.9 - 20.9)² + (99.9 + 20.9)² )/(99.9 x 99.9 + 20.9 x 20.9) = ?
...If (a – 8) 2 + (b + 2) 2 + (c – 3) 2 = 0, then find the value √(a +b + c).
...? + (35)² = (130)² - (45)² - 2850
