- Complex numbers are square roots of negative numbers. They are expressions that consist of both the real and imaginary axis.
- The general form of a complex number is expressed as z = x + iy
Given the complex number v = 6i + 3j,
10v is expressed as 10(6i + 3j)
10(6i + 3j) = 60i + 30j
Take the modulus of the complex number:
Hence the values of ||-10v|| is 51.96 units
