he number of integral value(e) of x satisfying the equation

1.	he number of integral value(e) of x satisfying the equation \| x3-.51x4 ax-254.3k-2.5*-1 is(C) 1(D) infinite(R) 3
Answer» the terms in the modules is written same as in R.H.S so, after substituting it with t , we get \|t\| = -t this can only be true when t = 0 , because modulus can't be -ve.. so modulus should be 0 => x⁴.3^\|x-2\|.5^(x-1) should be equal to 0 this true when x = 0 so, only 1 integral solution.. option C

Answer»

the terms in the modules is written same as in R.H.S

so, after substituting it with t , we get

|t| = -t

this can only be true when t = 0 , because modulus can't be -ve.. so modulus should be 0

=> x⁴.3^|x-2|.5^(x-1) should be equal to 0

this true when x = 0

so, only 1 integral solution..

option C
