Question

1. If (-2+ ✓-3) (-3+2√-3) = a + bi, find the real numbers a and b with values of a and b, also
find the modulus of a + bi.
​

Answer 1

Answer:

Step-by-step explanation:

(-2+√3i)(-3+2√3i)=a+bi

solving LHS , (-2+√3i)(-3+2√3i)= -7√3 i

a+bi= 0-7√3i

a= 0, b= -7√3

modulus of a+bi is = (0+(-7√3)^2)^0.5=7√3
