Q. What is the modulus (absolute value) of 6−8i ?Don't round. If necessary, express your answer as a radical.∣6−8i∣=
Understanding the modulus: Understand the modulus of a 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 mathematical terms, ∣a+bi∣=a2+b2. For the complex number 6−8i, a=6 and b=−8.
Calculating squares: Calculate the squares of the real and imaginary parts.Square the real part: 62=36.Square the imaginary part: (−8)2=64.
Adding squares: Add the squares of the real and imaginary parts.Sum of the squares: 36+64=100.
Finding the modulus: Take the square root of the sum to find the modulus. The square root of 100 is 10. Therefore, the modulus of 6−8i is 10.
