Q. What is the modulus (absolute value) of −6+4i ?Don't round. If necessary, express your answer as a radical.∣−6+4i∣=
Calculate modulus of complex number: The modulus of a complex number a+bi is given by the square root of the sum of the squares of its real part (a) and its imaginary part (b). In this case, the complex number is −6+4i, so we need to calculate the square root of (−6)2+(4)2.
Square the real part: First, we square the real part: (−6)2=36.
Square the imaginary part: Next, we square the imaginary part: (4)2=16.
Add squares of real and imaginary parts: Now, we add the squares of the real and imaginary parts: 36+16=52.
Take square root of sum: Finally, we take the square root of the sum to find the modulus: 52. Since 52 is not a perfect square, we leave the answer as a radical.
