Question
In a certain code language, ‘890’ means ‘provided
itself produce’, ‘825’ means ‘any for produce’ and ‘607’ means ‘change itself strength’. Which digit in that language means ‘provided’? ÂSolution
‘890’ - ‘provided itself produce’  …..(i) ‘825’ - ‘any for produce’    …..(ii) ‘607’ - ‘change itself strength’   …..(iii) From (i) & (ii) we get ‘8’ means ‘produce’. From (i) & (iii) we get ‘0’ means ‘itself’. Thus, in (i) statement ‘9’ means ‘provided’.Â
Fing the value of:
[(1024)(n/5) × (4)(2n+1) ] / [(16)n × (4)(n-1) ]
if 2x +3y =7 and 2x+2 -3y+2 =7, then find the value of x and y.
If, 6x + y = 20, and 2xy = 32, and 6x > y, then find the value of 216x³ – y³.
[a/(2a²  + 5a + 2)] = 1/6 , then find the value of (a+1)/a ?
- If (x - y) = 4, then find the value of (x³ - y³ - 12xy).
If x – 1/x = 9, then x3 – 1/x3 is:
If p = 25 - q - r and pq + r(q + p) = 189, then find the value of (p² + q² + r²).
If (a + b) = 1 and (1/a) – 2b = 5/a then find the value of a2 + b2.
If x = 35, then the value of x5 - 36x4 + 36x3 - 36x2 + 36x - 1 is
