If   and  where a, b, c are all non – zero numbers, then x equals to

A complete factorization of x⁴+64 is 

If p³ – q³ = (p-q)[(p-q)²+xpq)] then the value of x is

If then the value of x

If P = 99, then the value of P(P²+3P+3) is

When a number x is divided by a divisor it is seen that the divisor = 4 times the quotient=double the remainder. If the remainder is 80 then the value of x is

If then the value of is

  and then the ratio   equal to:
