If g(x) = 4x - 4^x, what is the value of g(3/2)?

g(x) = 4x - 4^x

so

g(3/2) = 4(3/2) - 4^3/2

g(3/2) = 6 - 32

4^3/2 = -26

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.
