5 different ornaments were made and 5 boxes, one for each with the names of the ornaments written over them. In how many ways can one put one ornament in one box such that exactly one ornament is in the wrong box?
The correct answer is D
If, p³ + q³= 485 and (p + q = 5), then find the value of [(1/p) + (1/q)]
If x = 99, then the value of x5 - 100x4 + 100x3 - 100x2 + 100x - 1 is
If x² + x = 11
find (x+4)³ +1/((x+4)³)
If x2 – 5x + 1 = 0, then find the value of {x2 + (1/x2)}.
If x + y + z = 4, xyz = 6 & x2 + y2 + z2 = 8 then find the value of x3 + y3 + z3.
What is the square root of the following?
(x² –12x+36) (x² + 8x + 16)
If x2 – 8√2x + 1 = 0, then what is the value of x3 + 1/x3.
If x2a = y2b =z2c≠ 0 and x2= yz, then the value of (ab + bc + ca) /bc is :
If x2 – xy + y2 = 16 and x4 + x2y2 + y4 = 320 then find x2 + xy + y2...
