What is the Standard International Unit (SIU) of measurement of light (Illumination)?
Lux (lx) Lux is basically the unit of illumination and is equal to one lumen per square metre.
If x = 3 + 2√2 and y = 3 - 2√2
Then find the value of 1/(x+1) + 1/(y+1)?
If 3y-3/y=18 then find the value of y² +1/y²
If x2a = y2b =z2c≠ 0 and x2= yz, then the value of (ab + bc + ca) /bc is :
22% of ‘x’ is equal to 66% of ‘y’, then find the value of x: y.
If x + y + z = 7, x² + y² + z² = 85 and x³ + y³+ z³ = 842, then the value of√3 xyz is:
...The average of three numbers a, b and c is 2 more than c. The average of a and b is 48. If d is 10 less than c, then the average of c and d is:
Find the value of
(1 - `1/(p+1)` ) + (1 - `2/(p+1)` ) + (1 - `3/(p+1)` ) + ........................... + (1 - `p/(p+1)` )
If x = (2+√3)/(2-√3), y = (2-√3)/(2+√3)
Then find out the value of (x²+y²-xy)/(x²+y²+xy)
If P3 + 3P2 + 3P = 7, then the value of P2+ 2P is –
If (a3+1)/(a+1) = (a3-1)/(a-1) and a ≠ 1, -1. Find the value of 'a'
