Q. What is the modulus (absolute value) of −12+5i ?Don't round. If necessary, express your answer as a radical.∣−12+5i∣=
Calculate Modulus: 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 −12+5i, so we need to calculate the square root of (−12)2+(5)2.Calculation: ((−12)2+(5)2)=(144+25)=169
Find Square Root of Sum: After calculating the sum inside the square root, we find that 169 is a perfect square, which means that the square root of 169 is an integer.Calculation: 169=13
