what is the coeffcient of this expreassion 17 - 2^3 + 5j

The coefficient is the numerical value that is multiplied by a variable or imaginary unit in an expression. Taking the expression 17 - 2^3 + 5j, there are no variables present, only a real number (17), an exponent (2^3), and an imaginary unit (5j).

The coefficient refers to the numerical value being multiplied by a variable, so in this case, since there are no variables, we can say that the coefficient is 17.
