A/B = 3/(4 + i) = 3/(4 + i) x ((4 - i) / (4 - i)) = 3(4 - i)/(16 + 1) = 3/17 x (4 - i) = (12 - 3i) / 17.
Let A be a 2x3 matrix and B a 3x2 matrix. If AxB and BxA both defined and determinant of the matrix AxB is 4, then evaluate the determinant of the matrix BxA.
If a, b, c are three real numbers such that a + b + c = 7, a^2 + b^2 + c^2= 35 and a^3 + b^3 + C^3 = 151. Find the value of abc?
