When simplified, the expression open paren x raised to the 1 eighth power close paren times open paren x raised to the 3 eighths power close paren is 12 Which is a possible value of x ?

When multiplying powers with the same base, add the exponents: x^(1/8) · x^(3/8) = x^(4/8) = x^(1/2). Since the expression equals 12, √x = 12, so x = 12² = 144; the possible value is 144.
